Megiddo, don't forget, since Stickly wrote XGUI, many people don't know there is a configuration file.
Seems most never read the <project>_readme.txt file located in the addons folder to know, or miss that detail.
Vizzy, all, please, though we added XGUI to make it slightly easier, ULX is so much more than just a pretty menu.
See many of the configuration items that ULX can do in gmod/data/ulx/config.txt .
If there is no file there, copy the default one from gmod/addons/ulx/data/ulx/config.txt to the gmod/data/ulx folder, then read/make any edits/restart server.
