Group system is also important for teams, It could be more interesting if you add:
$grm = It will show you the nearest group member.
/grbk or /gbk = Basically the same as /bk for cops but this one will work only for group members.
(If you add this /bk pls add a shortcut like "B" button, so when a member call a bk i just Press B button and automatically starts a GPS route to the member)
Also add a green blip on the radar for all groupmembers, and the Green blip have no radar limit so we can see from minimap where to go (n/s/w/e) for meet a mate, this could be very helpful during a chasing where a member Is in trouble and cant type in /g and just follow the blip on radar to find help.
