I would suggest adding a hotkey to toggle the function on and off.
While useful for detecting where bottlenecks are at a glance, having it on by default all the time is an eyesore, especially on big bases.

I agree to this!

Good idea. i'll look into how to add a hotkey.

Yes, please - and/or a GUI button !
(For show/hide, though for enable/diable would be nice too !)

Check out your in game settings for the keybinds -- they are there.

I believe by default Ctrl + U hides the labels, and Ctrl + Shift + U turns the mod on and off.

Whoops my bad - somehow missed them - still not used to the 0.17 menu yet ? (IMHO 0.16 one was better !)
