Hi,
when building some browsers, I often find that it would be useful to react in some way
while choosing one tab.
For instance, in glamoroust codebrowser (the "standard" one), when you choose
between "Instance" and "Meta", you should react in some way, to
display class definition or class instance definition (just like regular browsers).
AFAIK, currently there is no way to achieve that. I think adding some protocol
(#onSelect:, for instance) to composition presentations, has some sense... what do you
think?
cheers,
Esteban
