Moving from PEX to this plugin, everything in LuckPerms is far more in-depth and superior...until I used /lp listgroups.
Sure it's printout in-game does what it is intended to do (list the groups), but could defiantly have room for improvement. PEX has a printout that save's a lot of time when trouble shooting, or to quickly check a parent, group weight, ladder etc. I believe this would really benefit LuckPerms.
This would also be handy/apply to /lp listtracks.

Cheers for reading, and hopefully considering this change.

So, what information should it show?

Group name - Weight - ????

Cheers for the quick reply :)

In order of the lowest group (default) to the highest:
Group Name - Group Weight - Track Order/Name - Parent

Example:
Default - #10 - 1 | Ranks - []
Guest - #20 - 2 | Ranks - [Default]
Member - #30 - 3 | Ranks - [Guest]
Pro - #40 - 4 | Ranks - [Member]
Staff - #50 - 1 | Staff - [Pro]

I know it can look messy in text, but once you have it applied to an actual permissions system - it looks a lot cleaner and a great tool for a quick go-to to get basic information on your servers groups.
