Fantastic app mate!!! Its one of my most frequently used applications!!! Thanks a lot for making my N900 so much more awesome!

Just some suggestions...
1) Would it be possible for you to reduce the touch and hold time for the context menu a bit? Or atleast making it configurable via settings.
2) Also, as @Weedalot was suggesting, i personally feel the systems default implementation for multi-select dialogues is a little better in usability.
3) A file/folder details menu and configurable keyboard shortcuts can also be nice additions too.

Would love to see this application develop further if you have the time. Sorry if i have repeated some previously mentioned stuff as i haven't gone through all the pages of this thread.
