Excellent. Btw I think this plugin needs a more complex wiki, with all the commands and many examples, because it's really useful and wiki may be very helpful as well. Thank you!

Hello Auther!
It's a great plugin if the execute ... run psudo command can run normally on 1.19.3.
I'm sorry to tell u that I can't use either the auto fill up of execute ... run psudo even psudo can't follow the execute ... run, minecraft make every psudo, psudoas, psudoasop.... follow the execute ... run turns red to tell me it's wrong.
I tried ingore this notice and force it to run execute ... run psudo, unfortunately it report me it's a wrong code.
What need I do to use psudo after execute run?Or is this just a bug in 1.19.3?
My minecraft server version: purpur1.19.3, my plugin version:1.0.31.
Sorry for my poor English, hope to receive u reply. :)

Works perfectly! Love it!
I mainly use it to allow players to add themselves to certain permission groups by just standing on a pressure plate, since we use those groups for different tribes. Also comes in very handy from time to time whenever I need to execute a command for some random plugin for all (or nearby) players!

Good plugin, but I think it needs a name changing, "Fork of PsudoCommands" makes it hard to find on the forums!

Love the plugin
what about adding "psudoasop" for executing as player as op? this will fulfill this plugin
