Bug no.6
Bottom left - text overlaped by coords
Top right -
"Synchronizovat" - well It's personal preference but "Synchronizace" seems better to me
"Spouště" - In every Arma game there was "Spínače" what is reason to change?
"Pokročilý průzkum" - doesn't sound good, really, something like "Info o misi" sounds good to me
