I think it'd be nice that if and when we inevitably get the option to set a skills cost(as that seems to be something we'll get soon) we could access and edit both, which of the user's stat's it's using as the cost, and how much said skill costs in general via script. There doesn't have to be a dedicated scripting node for it(not yet anyway) but it'd be nice to have the option right out the gate. Oh yeah, also maybe an "unequip skill" function, alot of games have the ability for the player to unequip skills, and also a... default skills thing like the defaukt equipment
