I mostly play turn based JRPGs. My main gripe with any video game is excessive interacting with menus and inventories. I want to play a game, not enter submenus of submenus to change minute things. So here’s some features to combat that:

Queues: lining up research or skills to learn, so I don’t have to enter the fucking menus after every battle/minute.
Skill/Equipment sets: let me save my setups. Give me a few slots, and a warning if some part of that setup is used by another character. Heck, give me a way to save whole party setups, so I can have e.g. fire-killer team of ice-themed abilities on all characters. Or just have a standard ability set for progression and a second, temporary one for skill learning or whatnot.

Chained Echoes and FFVIIR had some good QoL improvements, but how many times do I have to shuffle materia or accessories, just because I’m leveling something? Every second encounter, because something is maxed and I have to swap it out for something else?

And Inventory management, that can make or break a game. Some of those submenus take half a minute to enter before you even do anything. Astria Ascending (I don’t recommend) was awful in that regard and guilty of everything mentioned above.

Fucking menus man… Give me some elaborate customizable skill setup slots and queues, please.
