Hi. I was wondering if, with the current 3.0.0-ALPHA5 src, it is possible for commands to show possible completion pop up when typing. For example, if I start typing /tp, in vanilla, it will show a list of args to follow that command, whereas in Pocketmine, it just says "[args:string]". Thanks!
The method used by BoxOfDevs is hacky and very unsustainable. It is only necessary when the commands are registered by other plugins.
