Bro, that was super informative, thank you so much!
With the descriptions you provided, I think I can create something that suits you. I think it would be awesome if you could press a key on the map and your skill list would appear, and you could drag and drop them into the skill shortcut box.
I've played Guild of Wars, and it's a standard feature in most MMORPGs, so I'm familiar with the general mechanics.
I think it would be interesting if we completely removed the standard RPG Maker menu, including the native Attack, Guard, Item, and Escape functions, creating two shortcut lines, one for native functions and another for skills. This way, the entire HUD would be recreated and would match the new elements.
I can make the two lines independent and allow you to position each one with its own offset, making it possible to customize your HUD in the best way possible.
What do you think?
Thanks again for the suggestion and for all the clarifications! That was amazing!
