They already did a big overhaul of the achievement window itself with Endwalker, but there's always room for improvement. I like some of the ideas in this thread already, like having multiple titles on the adventurer plate, or having small HUD widget with a few achievements that you've got pinned to your watch list. And more stuff from the Keeper of the Roles.

I'd immediately have my Tankless Job for WAR pinned achievement on that widget. That grind to 700 is real, and I bet its about to hit 900 or 1000 with Dawntrail....

That said: I've had the best luck with my UI suggestions going into the UI specific forum, not general discussion. Several of my requests made to the UI section here on the official forums eventually made it into the game, much to my delight and joy. https://forum.square-enix.com/ffxiv/...User-Interface
