When I drag and drop a file (or worse, a folder) onto Yummy FTP, it often gets uploaded twice at the same time. I think my Wacom tablet is sending two drop events for a single drop, so it's probably not your bug, but if you could check whether a file or folder is already in the cue being uploaded to the same location and only do one of the uploads, that would be great for me.

While the ability to set permissions recursively is useful, I'd like to have the option to turn it off by default.  I don't know how many times I've accidentally set the executable bit on all the files in a folder when I was intending just to change the permissions on the folder (and not on any subfolders). And I wouldn't even have realized I was doing it except that I got an error message when the setting of permissions on a subfolder owned by another user failed.  Great feature, but needs more control. Thanks.
