Auto-updating the browser while changing tags without revisiting nodes on a tree

Hi,

I'm working on my project Grafoscopio, to provide a outliner/notebook
like experience to write and visualize data. Details can be found on [1].

I want to create modal nodes by tagging them, so If I mark a node like
code it can behave like a workspace and execute code. You can see a
small demo of this feature on [2]

[2] https://archive.org/details/grafoscopio-tags-alpha1.mp4

My code for tagging nodes is this:

==[a]=============================================
UI>>addTagsTo: a Node

        "Tags the node passed as argument with a value from the collection of
tags available"
        | selection |

        tagsAvailable isNil
                ifFalse: [
                        selection := UIManager default chooseFrom: tagsAvailable title:
'Elija una etiqueta'.
                        aNode tagAs: (tagsAvailable at: selection)
                        ]
                ifTrue: [self messageNoTagsAvailable].
        browser update.
=================================================

But I have three questions:

i. How Can I update the nodes views/behaviour without revisiting them?
The code in [a] is updating the node trees, but not the particular node
views.

ii. How can I made the code in a node tagged as "code" get executed?

iii. Can I embed playgrounds instead of workspaces in a browser pane,
with the possibility to explore objects and get more details about them?

Thanks,

Offray

Yes. I want that when I tag a node, the corresponded view in the right
side updates automatically without the need to revisit the node to see
the changes. As shown in the video at [1][2], this is what I need to do
right now.

If I can embed a playground inside the view, they should be executed
when the play button of the playground or its shortcut are used. I need
to make more tests with the code you share with me on this mail for
embeddable playgrounds.

Thanks I have made some small modification, so when you click on an
empty place (which is so common) of the left pane it doesn't raise an
error stack. Here is the code:

Now I would like to change the list by a dictionary and to use embedded
browsers to made the code more modular and applicable to my needs. I'll
keep you posted.
