This isn't so much a QoL suggestion as more a basic common sense suggestion.
When talking to Temptrix and verifying which NMs you've killed for Aeonic Weapon progression, there's no obvious method of closing the menu. No "Cancel/I'm done" option. The only options are "Show me what I've killed" and "I'd like to give up entirely" The latter of which cancels the quest all together. Even using the ESC key doesn't close the menus. The only way to close the menus is to click on one of the enemies listed under "Show me what I've killed." That is absolute garbage.
I would just like to point out how unbelievably asinine that menu layout is. And what's worse, it caused one of my friends to cancel her weapon because she couldn't find any way to close the menu, even when trying to just ESC out of it. She clicked the only option that seemed to suggest "cancel" which was the "I'd like to give up entirely." Yes there were several warnings asking for confirmation, but the fact that the menu can't be closed with ESC when the majority of menus in this game can, and there was no obvious "cancel/leave" option in the menu, she went the only option that seemed HALFWAY logical.
50k beads and progress already made were thrown away by terrible menu design. I have to say this is the most disappointed I've ever been in the design of this game, and it's due to a damn poorly laid out menu.
