Pretty low priority, would be cool though.

Some examples

/lp user <user> promote <track>

Currently checks for luckperms.user.promote

Should be changed to check:

• luckperms.user.promote.<track>.<group promoting to> (if false return, if true allow, if undef continue)
• luckperms.user.promote.<track> (if false return, if true allow, if undef continue)
• luckperms.user.promote (if true, allow, otherwise deny)

Should be the same for demote.

/lp user <user> parent add <group>

Currently checks for luckperms.user.parent.add

Should be changed to check:

• luckperms.user.parent.add.<group> (if false return, if true allow, if undef continue)
• luckperms.user.parent.add (if true, allow, otherwise deny)

Should be the same for permission equivalents.

How to determine whether players can actually use the command

I guess this should be achieved through parsing the command string directly. Instead of doing the check at execution, it will be done ahead of time.

This would be really useful imo.

I would love this to be added, but also with /lp user user parent remove group and as permission luckperms.user.remove.group
