New button and hotkey

[Aizark]

I tried to do handmade craft. The player would press the hotkey, and an event would be triggered with the opening of the crafting station window.
Unfortunately, in the event management menu, you cannot check which key the player pressed, so I cannot call the window.
How at the moment can you add new buttons to the global management menu, next to inventory, spellbook, and so on?

My suggestion for this would be to check out the source of the engine and build it yourself, or pay someone else to do it.
