I use a macro for mine when I'm raiding or doing dungeons, etc. You can tweak it as you like and add stuff or remove as needed. Example below. Useful for when you want to keep only combat related UI shown and hide the rest.
/hud dlist
/hud tbar
/hud gil
/hud igrid
/hud mmenu
/hud ebar
/hotbar display 4
/hotbar display 5
/hotbar display 6
/hotbar display 7
/hotbar display 8
