Here is a list of things that I think should be added to Slayer:
>Respawn button
-A button next to "Move" and "Remove" that simply respawns the selected player
>Kill button
-Same as respawn button, but instead it kills the selected player
>White listed teams
-A drop down box for each team where you select the trust or admin level the player must be to join that team
-It would include: Anyone, BL_ID Allow, Build Trust, Full Trust, Admin, Super Admin, Host
>Randomize teams
-Shuffle teams makes everyone on one team switch to the other
-Randomize teams would completely mix the teams up, this way you aren't with the same players all the time
>Pre-round countdown for teams
-You can set how long a countdown is separately for different teams
-Could be useful for TDMs where there is an Attacker and Defender team and the host wants the Defender team to have time to set up and get ready before the Attackers come
>Advanced team leaders
-Team leaders are available
-Separate team leader window where you can choose: leader's weapons, playertype, uniform, respawn time, # of team leaders possible, lives, playerscale, maybe amount of points for killing the team leader
-Also includes check boxes for: Can use team chat, build, paint, wand
-You can create multiple leaders and you can type in the leader's rank
-Leader, Co-Leader, Captain, Co-Captain...etc
-Shuffle or randomize leader
-Selects a new leader randomly after certain amount of rounds, similar to shuffle teams
-Leader spawn point brick
-It would also be really cool if after a certain amount of rounds, your team can vote for who they want to be the next leader
-If there is a tie it randomly chooses between whoever tied
You can leave your own suggestions and I might add it to the list.
