Notification before deleting folders

I have way too many folders and duplicate files in my Dropbox, but as I'm cleaning them out and trying to delete folders, I'm finding the process clunky.  Because I don't have all my files on my computer, I'm using Firefox browser with my Dropbox open in a window.  I'm trying to be careful not to accidentally delete any files, but there is no way to delete a folder with the folder open.  You have to first click out of the folder to the level above it, then delete it.  My suggestion is that you improve the ability to organize files, whatever that ends up looking like.
