For anyone that wants to use this script:
It works wonderfully and as planned, BUT it has an issue that collides with the Blizz ABS.
Using the Blizz's $game_system.hotkeys = false command to Hide either the HUD or the Hotkeys breaks the game. It doesn't even crash, it completeley freezes.
Weirdly enough, it doesn't happen by using the Hud and Hotkeys key to toggle their display.
I'm trying to fix this issue but i haven't been able to achieve it yet. I'm really unexperienced at this.
If i find the solution i'll post it ASAP. If anyone more experienced than me has some free time (i'm not asking for miracles, this post's been dead for like 4 years) any hand will be more than welcome.
