This mod adds a slider to the top left of the screen to control the speed bonus of your exoskeletons at will, that automatically shows and hides itself along with your inventory or armor grid as long as you have any legs equipped. So no legs means no screen clutter :D
Optionally can be configured to stay visible without needing the inventory/armor to be open, through the tickbox in the per-player runtime mod settings.

Should any issues or errors occur, please do report them in the discussion tab so I can take a look :D

Attached screenshots have a buncha other mods' toolbar buttons visible: this mod does not add any such thing. It only adds the slider on the top left when legs are equipped and the player has the GUI of either their inventory or worn armor opened.

Though this mod was completely rewritten from scratch, it is based on a mod originally by royalmustard and xelantro.
