I really don't mind the text in the loading screen, the text that says in which area I'm in. Some other texts are ok as well.
But I definitely don't need the retainer messages in the middle of the screen all the time, or things like that a FATE is nearby, or how many search results were found.
I would love an option to turn off at least some of them if not all, so that they appear in the chat only, and also the option to move them away from the middle of the screen.
What annoys me the most are those dialogue bubbles from NPCs that sometimes appear during battle. I tend to miss them because the location they're in is garbage. I have all the important info together on my UI and those are in a really bad position on the screen. I always have to read all the dialogue in the chat afterwards. I always wanted the option to reposition the dialogue ever since 2013.
I recently heard the UI team only made the gpose stickers because they had nothing else to do. If that's really true they should definitely take a look at the UI forums. There are so many good suggestions, a lot of them surely very easy to implement.
