Hum, question/feedback about multiple selection.
You added the multiple selection move.
No kick with multi-selection, no server group add with multi-selection.

I have an example about the server groups idea.
If you have some rights (server group) like association member, team member and maybe the team's game and you want to authenticate the team's x players.
Imagine, you create a LOL (or CSGO, ...) team with 4-5 members. You need to click on each member and add manually each servergroup (in one time with the servergroups dialog box).

For myself, I developed a bot or sometimes I use YaTQA ( <3 ).
But why not make it simplier and use the multi selection for more features ?
