Hi Herby - for #1, yes you can do that (I do this in PharoLambda) - there was a snippet from Sven on how to do it (you need to override 2 classes I seem to recall) , if you search in the archives you should find it.
I'm not near a computer to give you the exact bit - but if you can't find it I'll pop a reply tomorrow.
