I have a few ideas that may or may not interest you.
1. Ops can have different glowing color effects "Any Staff color wouldn't apply" Instead of the normal White we've always had.
(At least to my knowledge white is the only glow effect we've had for OP)"
2. Ops are given the command /rd /md If no admins are present Incase someone drops a whole lot of entities or spams a crap ton of immortal mobs, Ops can clear it instead of asking for an admin.
("The command is only given when no admin is present/online")
"If an admin joined the game, The command would reverted back to normal henceforth, Ops are no longer allowed to use /rd /md. after an admin joins
3. a command that allows an op to remove invisibility from all individuals invisible
-> An alternative version of /invis smite
-> /invisr | invisibility remove | something along the lines of that. | Removed from other ops only.
(Possibly griefing/trolling/etc. | If no admin is present/online to take action, Ops can take it into their own hand to catch the culprit )
(This would help with reporting them if /near doesn't work so then there is a more easy way to know who did it)
( Since invisible players name Disappear )
Everything said with " " Applies
/near doesn't work fix it.
However #3 might be useless because: Admins can view grief with coreprotect Right?
These are all I have for today I might think of some more stuff that could benefit the server.
People who are invisoible have a 60% chance to get away with something if the user was not online to catch them griefing their build.
(But with that command they can catch their username in the act and report it rightaway)
or #Coreprotect for the save. - This is also my first time using forums so Eh sorry if it looks bad
