While I played with different layouts last night, I've noticed a strange behaviour that is probably a bug. I do not have enough experience to bring it to bugzilla, so do it for me, if you can repeat the same effect.
I need to have too layouts — for Cyrillic and Latin script. While choosing among different options, I've noticed that the additional layout (Russia os_winkeys in my case) works ok, while the first layout (selected via Yast2 in the upper list)
resets to the first layout in the list (Montenegro in Russian interface) every time I enter the keyboard options to edit them. The previously selected keys to shift layouts also seem to get lost at every visit to the keyboard settings. That is obviously not very comfortable, because one can come to the settings just to make a smaller change, not to renew all of the settings.
Sorry, if the description is not very clear: neither I have much experience in describing computer problems, nor the language is my native
