HUD Preview

I didn't see this come up in my searches, but it would be helpful if we could preview our HUD, especially for the elements that are not present all the time, like the enemy list/party list etc.
Since the items in these list can vary, I was thinking something that would ask for user input, such as the number of enemies to display in a list, and then execute a test list based on the current HUD, or the maximum the list can display.
The outlines of the elements in the HUD can be deceiving, which makes it difficult to place things efficiently without getting into a raid or something and fiddling with it then D:
