Make it Midnight Commander friendly
It is virtually impossible to work reasonably fluent using Midnight Commander. It would help if I had a return key on the function and arrow keys page. Currently you have to constantly switch between the function key page and the keyboard in order to reach the return key.
Also, the keyboard is far too big. In landscape mode it takes more than 50 % of the screen space - one third should be big enough and give me more space to see the data what I actually want to work with.
