Hi lyes, also re: having something show up when a particular item is selected - in v3 I'll probably be adding a selection indicator into the scene browser for that, most likely as a dot along the right-hand side of the entry. That would also probably be where you would click to do selection while clicking on the main text area will probably pop out a menu with some additional tools on it.

See this previous thread for some discussion on it:
