Ban
It would be nice to see who banned a person and be able to put in notes on why/how long, etc. This way, all folks with ban privileges would be on the same page, even if they aren't on the same schedule. Additionally, it would allow members to have a basis for review by other officers/leaders/admins, having the info right there as to why and when.
Having been a part of guild leadership since before most were calling them guilds, I know that each one is unique, along with what permissions are granted to various levels of leadership. Having information to implement checks and balances with is never a bad thing, and can often point out trouble brewing and allow it to be diffused before it hits critical mass.
This is something we may revisit in a future release, but isn’t currently planned to be in a development sprint.
