Hmm...
right now I have one burning question: Why build a completely new layer of indirection with different API instead of improving and extending Roassal (=Telescope alongside Roassal instead of on top of it)? It seems like a lot of effort went into creating it while it would have had bigger and better impact in Roassal...
Roassal has RTGroup, which is obviously less powerful, but often enough. Plus the "if node matches this add/change/do this" that is also implemented by Telescope.
Roassal updates only what should be updated, not the whole visualization. (And if some particular builder does rerender everything, that's the builder's problem.) After all this is transitive --- if Telescope can do partial changes and is on top of Roassal, so can Roassal do it...
I saw the presentation at ESUG but I wanted more insight (or documentation)... Anyway, I'll continue my exploration... but the idea that I might need interaction between Telescope and Roassal elements and concepts doesn't make me happy...

On another note... why no inspector support?

So there is TLStyleSheet>>compositeExpandedByDefault: But what if I want for example to have the option to manually resize something? Roassal gives me RTResizeable. Would I have to write some special TLInteraction or can I somehow reuse what Roassal offers? (This also applies for Roassal interactions in general).

Because we created Telescope when we had to move from Roassal to Roassal2 and at this time Roassal2 was not supporting a Mondrian like syntax so we tried to create an equivalent powerful syntax than Mondrian with an object oriented approach
Because we are creating really interactives visualizations we were always out limit of RTGroup
Yes but Telescope does it for you...

Because you cannot just open a Visualization like that; it requires some datas. A good idea would be to have some examples data with each visualization

What do you mean? The datas were introduced to the object already, this is same like calling "visualization open". Or maybe I am treating TL scripts too much like Roassal scripts with different API.

Because we created Telescope when we had to move from Roassal to Roassal2 and at this time Roassal2 was not supporting a Mondrian like syntax so we tried to create an equivalent powerful syntax than Mondrian with an object oriented approach I do understand this but that's not what I am asking. Why not create it alongside Roassal2 instead of on top of it; or just create a better Mondrian? What I am trying to understand is what is the benefit of introducing a whole new level of indirection just to simplify one thing, instead of improving the underlying layer in the first place. Because I feel that I am loosing a lot of power because Roassal is hidden from me. And this got overlooked probably (relates to the question above): So there is TLStyleSheet>>compositeExpandedByDefault: But what if I want for example to have the option to manually resize something? Roassal gives me RTResizeable. Would I have to write some special TLInteraction or can I somehow reuse what Roassal offers? This also applies for Roassal interactions in general. And even for Roassal in general... e.g. RTShape allSubclasses size. "30" TLSimpleShape allSubclasses size. "3" So if I wanted to use some other shape from Roassal (for example box with rounded corners), would I have to create matching TL shape and then define mapping in the generator/connector?

At this point you are not sure that data were introduced, I can do TLButterfly new inspect and then it will not work because I didn't put datas in my visu so generate will fail. In addition it's not a good idea to generate the visualization without the user approval especially if he is debugging an infinite loop for example ;-)
Because Roassal2 was creating a whole new model (RTGroup instead of RoGroup)... Obviously you are losing some power because Telescope is not a drawing framework nor Roassal functionnalities copy, just a visualization framework and Roassal is just used as a renderer (the goal of the connector is to create easily new ways to render our model; in Bloc or html5 for example). We faced lots of difficulties when using roassal as a visualization framework especially with interactions that modify the model and so created a model specialized for that, that offers much more than just "simplifying one thing"; just try to create with roassal the demo #exampleMovingNodeToAnotherGroup and you will understand that many things are impacted. Scripting philosophy was also problematic for us because we have to maintain lots of visualizations and observe that we were copying/pasting lots of code that was complicated to keep up to date. The abstraction of Action/Interaction composition was really reward-full with composite nodes especially.
compositeExpandedByDefault is not about resizing; it is about showing children of a composite node. Resizing is just a side effect because currently Telescope make some room for that (maybe a better strategy would be to create smaller elements for children and not resize parent). If you want to resize something, just change style with TLStyleCustomizationAction.
In my opinion, rounded corners are not another kinds of shapes, just a customization of existing and so should be a style attribute. Yes you can create your own subclasses of TLShape but Telescope is not designed to just make easier to use Roassal but to offer a bigger level of abstraction. Telescope is not about thinking in term of drawing but in term of visualization model.

telescope idea is that you can define visualization (model) where you can define advanced behavior and reuse it. We presented last year the model to alex and this year again and he saw that there is a real added value. Scripts does not let us reuse and build more complex model. Telescope has a visualziation model (not a canvas on which you write) + composite + advanced interaction. telescope model should be taken and used in future version of Roassal. We do not take it personally if alex takes synectique's code/ideas. For us we will continue to build around and if telescope is fusioned into Roassal 3 then even better. I dream about Roassal 3 = Bloc + Telescope + some part of Roassal 2 (layout....) And roassal 3 does not have to be compatible to Roassal2. And people do not have to migrate to Roassal 3.

Hi Stef, I do understand (at least partially) the value behind it and I tried to play with it more, and there were things that I really liked... However I feel like many of those concepts should've been introduced directly as part (or an extension) of Roassal, instead of top of it, because that seriously limits its (re)usability without fully committing to Telescope. In any case from my experiments and considering all other things (like serious lack of documentation, even smaller user-base, different API, ...), I think that it would be currently too much work for too little added value for me, because I already had to solve some of the problems you guys had on my own, so I would be basically spend a lot of time rewriting code and at the end I would be where I started... and then Roassal 3 would come and I would have to rewrite again. Also another important part is the overall user experience, so this definitely means that I will need to dive deep into Roassal (and even Morphic) to make things work (as I've already done and continue to do). And since you decided that you want yet another layer between Telescope and Roassal (to be able have another rendering libraries (although from the Telescope code I've seen it's not exactly separated)). So this would mean for me that I would have to write a lot of stuff twice (or three times (Roassal+Telescope+adapter)); and again, with little added benefit for me (and since I'm not payed for what I do; what I want is my primary concern). So to summarize... I think that currently best scenario is to postpone it and look at it again when Roassal 3 starts rolling around, because I will be migrating to Roassal 3 for sure also because of Bloc. This will also give me more time to familiarize myself more with Telescope and make the transition less painful.
