you are wrong. don't tell me i need to read forums more, i know enough (editing animations, textures and maps is a child's play). the 4 bars thing is NOT server sided. it's almost the same as if you switch your 1st bar to 4rd bar, since everything is just replicated except the hotkeys (and they are no hotkeys for 4th bar even on h5). my intentions weren't to censore the file, lol, just the path. i even said in 1st post it's engine.u . and why would i want to look into systextures for god's sake, the textures are all the same, they're just replicated for each skillbar. it's easy to hexedit the .u files, even 5 year old child knows that. harder is to actually ADD NEW ENTRIES to the .u files and only few guys knows that.
but yes, there is something regarding that also in nwindow.u, but probably not required to change, there are just the basic mechanisms, which are only replicated in engine.u.
p.s. i'm not using l2j i'm using l2off and i don't want to do any server modifications.
