Is there any reference in the wiki or anywhere else about who is working on what? If there isn't any it would be nice to make one, as right now it is not very easy to know what to do.
It would be nice, yes. Maybe there is something like a project task manager on SourceForge, where you create project tasks and assign to people. It would make a very nice TODO list too.
Or we could just make it on Wiki too.
Complete quick search / quick filter, as I think there are some features missing
At least needed is option for quick filter to work on directories/files/directories+files. And a case-insensitive option.
Separate every category from options form into a different frame (following the work started by Alexx2000)
Actually I started doing that just yesterday :)
