Dear FFXIV designers (and/or devs depending on how you do things at SE),

I've just spent a month affected by bug where I couldn't select "Use" on most of my items. Turns out the reason why is that I had my saddlebag open.

1. Not all items were affected, so why can I use some things but not most of the items?
2. Why does a bag being open need to block usage of items contained in DIFFERENT bags?

This is but an example of the many frustrating design choices you made.
Any design choice must have a reason. Especially when it affects gameplay.
FFXIV is overall a nice game, but it is the most frustrating one I have ever played. And not because of actual gameplay issues (beside the lack of a sticky-target feature). Because of hundreds of minor design choices that have no good reason to be that always have to do with UI, emotes, cinematics (and auto-skip). Pretty much everything that is not directly actual gameplay...
