You can opt to remove available skill types but for the battle scene UI, I tried to keep things minimally disruptive. This may change in future versions however.
This is because the menu builder plugin loads the pictures from rpg maker memory. I can implement an option to disable the pictures on scene start or scene end but going back to the previous scene means you will need to re-show them
Contact me on discord (Synrec), I'll send a key, following which, I may have to contact gotcha gotcha games after they return to office. Likely an issue came up when translating the plugin
