I hope this is at least destined for NGS if not PSO 2 classic, but one thing thats bugging me as I progress in the game and have more and more things in my sub-palettes is that the controls to switch and use an item or ability is a bit contrived. I have to actually press a key on the other side of my keyboard to switch to one of the specific sub-palettes, and if I miss, I've accidentally unequipped my weapons (because there's no apparent way to disable unused weapon loadouts?).
Basically, I would like it if there was an option that allowed Shift + 1-9 to call up slots on sub-palette 2 and Ctrl + 1-9 to call up slots on sub-palette 3 (could be configurable?). This would also allow me to quickly see the state of my abilities at a glance.
If I have my class abilities and techniques on sub-palette 1, for instance, I can see their cooldowns and activate them all there. On the off-chance I need to use an item or cast a rare technique, they're available on sub-palette 2 (and all I have to do is hold shift to use them, rather than toggling the entire sub-palette and risk fumbling it in the heat of the moment). This already works really well for my weapon actions, so having the same thing for the sub-palette would give me a lot more flexibility in high-pressure situations.
