like can i find and edit the power of say water gun?
no, not yet. its something i really want and i think nilllzz liked the idea too, not so much for editing our moves, but making your own versions of moves or completely new ones (ideally modders should leave our stuff alone and define new things, even if its just a copy of something exists with 1 change, otherwise your changes will break with patches and certainly wouldnt be able to play nice with other mods)
some time there should be a system for making moves and their animations to go along with adding custom pokemon (which is mostly working now), but that time isn't now
