Starts to looking good. But I suggest the you should be able to chose between advance folder view and basic. Where advance shows all the .folders and basic shows you MyDocs with the folders as shown in Maemo "File Manager".
I think people th5 like to use Ftp but not familiar with .folders find it much more easy to navigate.
Also the most common folders I use are .sound, tmp, .documents and .downloads so all the other .folders is just in the way for easy and usable navigating in local files.
Also a meny with your favorites thet connects you right away with one click would be nice.
A connecting and downloading progressbar would be nice.
