There should be some marking on the boss door, because when I'm set up as melee only (yellow) & suddenly find myself against the boss, with lazes & short range attacks & don't really get a chance to switch to any viable weapons before I'm dead.
Or maybe an option to set up "attack profiles" (probably a fun mechanic), so you can press like 1, 2, 3, ... or something & it automatically switches all notes to whatever is stored in that profile.
So you can switch from melee "brawler" to "sniper" with a single button press.
Optionally with some delay mechanic if this is "too overpowered", like the "play laser" has to pass one time to switch the layout (probably a VERY annoying mechanic).
