Couple of Features I Really Wish SE Would Implement

1. Separate history log for FC Chests. Separate lists for items deposit and withdraws and gil deposits and withdraws.

2. Item Preview System. This is really a necessary feature to make the glamour system better. Currently you can't see what an item looks like unless it is equipped.

3. The ability to select the amount of an item from a market board seller that you want instead of being forced to buy the exact stack number up.

4. Get rid of kick/abandon timers. There are times when either someone dcs or its just so obviously a fail group that you just sit there wasting time waiting for the timer to count down so you don't have to take a leave penalty.

3 is a seller feature that should not change.

There is an awesome thread for suggestions found here:
Some suggestions, mostly quality of life, obvious things

It's a lot of pages, the community has been keeping it going and occasionally a rep will chime in on various things within it. I'd suggest adding to that thread. :)

Great! Will totally do that!
