Just wanted to bump this thread - the lack of these features, in particular the ability to do a multiple select/drag in the project tree - were some of the very first things I noticed. Finding time to implement these features would *really* help polish the experience of maintaining a large project with C::B - having to bring files in at the root level and then move them one by one to virtual folders is onerous to say the least. In addition, C::B does not remember the previous folder files were added from, so I have to crawl through the entire directory hierachy every time I add anything.
My only other comment (right off the bat) is the decision to display the whole path of each file on the tab in the editor. When I'm looking at the editor tabs, I care a lot less about the path than about just the file name. Showing the whole path means fewer tabs may be visible at once.
In any event, I'm impressed and delighted by C::B. I am really hoping this will be the answer for a more comfortable IDE to use on the Mac (I'm not a big Xcode fan) and perhaps serve as an eventual replacement for Visual Studio on the PC as well. I know the C::B team probably has bigger fish to fry, but finding time to do a little polish will really make a world of difference, at least for me.
