Hey @Chew i think i can help with this new command , i have already made some minor changes in role comparisons, and i am currently working in the users comparison. I might also think of something new to add in roles comparison, like a better display of color or maybe showing the common role permissions (Let me know if you like any of those 2 suggestions). Your implementation in roles tho seems to be very complete!

Thank you for your contributions!
My current progress is on the command/diff branch, I believe, as I assume you know. There's really no point in showing if they have in common for role comparisons. It may be worth putting all the permission back in the %^roleinfo command (it just shows what the everyone role doesn't have, but this can be replaced by comparing the everyone role with the specified role now)

Feel free to toss a PR targeting that branch, and I'll be happy to review and merge it in! Feel free to hop on the Discord server if you haven't already.
