Hey bro , yes, and yes, you can use plugin commands during battles, provided they were designed to work in that context. You can also use a menu to assign shortcuts for your spells and abilities, configuring the entire system on a per-player basis; there’s an in-game menu for editing these shortcuts, and you can map them to controller buttons, while the on-screen icons support touch input.
If you want a system focused strictly on combat, I have another plugin called `koa_skillbar` that is more robust in that regard, handling only map and battle skills without the extra features found in other plugins.
