Well its not just for the default rxdata I actually wanted to make my own .rxdata
I was thinking about making Weapons like Actors being able to equip "gems", having health, etc. but in order for me to do that I'd need to mod RPG::Weapon and you'd have to use alot of
$data_weapons[id].gem1 = item_id
So if I had an editor that could do that for me than it'd be easier for me to get the script done and it'd also be easy to configure for people who use it.
