Yeah, I think you're right. (also, my PC sucks too, so you're not alone bro)
Maybe for a player with no experience in D&D 5e a lot of submenus would be confusing and less easy to approach, but right now the system may look fine to get in, but as soon as you reach lvl 3 it looks like a mess (wonder what would happen at lvl 10?).
Imho subemenus for each category could help the player base and give a fresh experience, but I get that this is not the first fix we need in the game.
Also that would prevent a great loss of time after every level up for the new bar setting (for every character).
Maybe it's not the right time for quality of life, but they're always appreciated
