In Studio you can open class with typing / pasting full classname Ctrl+O dialogs filenamebox.
in Open Atelier Class/Routine Dialog (Ctrl+Shift+T) you can't give full class name (package.class) and
when typing only classname part it does not give you any hint about package of those classes it shows.
Its' a bit frustrating when we can have ( and we have) lot of classess named similarily in different packages
and we have lot of packages so the tree crawling is a bit slow.
Other (un)related bug i noticed, AtelierExplorer views <Link with editor > -button does not work , it only selects
the main node from view). In Project Explorer it seems to do the right thing, eg open the tree from the rigt position and selects the class that is open in your last used editor.
But so far I'm quite pleased with how this looks.
