The customizable UI is awesome. It's one of the better convenience features I've seen in a game like this.

The problem I've been running into is all the hidden extras that are circumstantial. Especially since 1.19 sort of reshuffled everything.

For example, the "EXP Chain" graphic pops up where my party list is and blocks the top three members on the list.

The raid timer position reset and now pops up ontop of my minimap. There's not really time to mess with UI items while in a raid.

It'd be nice to see some sort of "display all" feature, whether in game or in FFXIV config" to allow us to properly arrange or UI with these circumstantial items in mind that way we don't have to distract ourselves from gameplay to try and catch these things.
