When processing a large number of files, it'd be nice to have some more information that ensures that "the program is doing things". Right now, the only that things are happening is watching what happens to each file in the status bar.
A small progress bar somewhere (not a popup, that would block the interface, the user should still be able to keep using the program while files are being processed) with the estimate progress of (files processed)/(total files loaded) would be cool.
Another side problem is, when I drag a lot of files (maybe 500, I'm not sure), the interface gets unresponsive for a while, around 20 seconds, and then keeps working like always. I'm sorry for the lack of accuracy, if it's needed I could try to provide more information later.
