Android file manager UI

i've tried all android file managers i can find, and none of them works for me. Most of them can go into one of two groups: so simple that they are missing some important functions, or packed with a lot of functions, but lack usability. Oh yeah, and most of them are ugly..

This is something i think will work for me, simple to use, easy to master, and would contain all essential functions.

Now if i could only find a coder..
