i'm on work but with a quick look i find somethink , u can try this ...
1.) edit ../coreui3/xml/CoreHHGroup.xml
2.) search for width="75" ..and change 75 to 72 ! -- line 258 , if my copy here is up to date
u didn't need to exit VG , so edit, change and save the file , then "/reloadui" ingame .. or restart
