FallUI - HUD Mod
MODEvery widget can be positioned and configured.
Optional (if you want to use an existing DEF_HUD layout): To import a DEF_HUD layout, just go into the MCM HUD Layout Manager and select "DEF_HUD.xml". (You can even open the editor and import it for further editing!).
But under certain conditions with specific mods it is incompatible with the MCM Layout Editor (can cause CTD).
