Hey, thank you!
The UI is kind of a work in progress, I mostly just slapped on the defaults that came with some moghunter scripts. I'm using RPG Maker VX Ace, I didn't have MV when I first started and by the time I got it I was pretty far into development and didn't really want to remake everything.
I definitely plan to rework UI at some point. One reason I am hesitant to do it soon is because I haven't fully fleshed out (or settled on for that matter) some of the systems in game and I'm afraid of having to rework it again once I do flesh things out more. So it's a placeholder for now!
I'm also a bit hesitant on adding specific keybinds for menu things as a lot of people even forget how to toggle the clock with "T" but the congestion will definitely be addressed.
