Outcast eventually aim to be like EssentialsX with more features. It Is very early on in development, and will hopefully be continued to be updated by me.
It Currently includes an updated version of some commands + a few more.

/gamemode/gm <letter/number/gamemode> <playername> - changes gamemode - outcast.gamemode
/clear/cl <playername> - clears a player inventory - outcast.clear
/fly - toggles to ability to fly - outcast.fly
/isonline <playername> checks if the player is online - outcast.isonline
/rel - reloads the server without asking for /reload confirm - outcast.reload + default minecraft reload permission
/whatami - checks if you are a player or the console - op

There is a custom join and leave message. I made a /cancel and global cancel witch would cancel an event like mining or placing, global cancel being all players, and cancel being a specific player, but the tab complete was taking to long, so i just published it. The same thing with a permission command. It would be /perm <player/group> <add/add> <playername/groupname> <permission> <true/false>, but I never got around to the tab complete. So that will come in version 2.0 probably.
