No unicode: Big missing feature although it can probably be added manually.
Button Bar Menus : I agree, with a small screen, space is crucial. Next release maybe?
No moving/resizing/modal stuff: I agree, this is just ridiculous but probably needs a lot of work.
No persistence: I also agree but I'm not surprised, had the same with gnome environment on my PC and that's one out of a lot reasons I left it for kde. Other big one being the lack of buffering (user space or helped by the kernel) when reopening already browsed directory for example.
