feedback on the documentation and gui

0) Thank you, nice appearance of the board and the clock. You excel here more than any online web site or any other desktop chess software.
1) I find it hard to click the menus. I have to hold the mouse button, otherwise they disappear. I believe this is known issue (you are working on a GTK version. Oh well, I am using GNUStep and someone needs to write another version for that, but such is desktop life.)
2) I find it VERY hard to alter any settings. I do not understand what level of the computer engine is (easy, intermediate, hard).
3) I liked the documentation. It is nice and thorough. 
4) But the documentation does not go through the engine or XBoard setting windows.
5) The documentation ought to be in multiple languages. I believe many GNU projects do it using GNUN (GNU United Nations), but I don't know how to use it. If you set up the architecture, I'll happily translate the website and the manual to Russian.
