This mod will toggle the player's run speed multiplier (applied after all bonuses) to one of three configurable values with a keypress (F6 by default, but configurable).
Could you update the mod for 1.1, please? I think a simple change of the factorio_version variable from 0.18 to 1.1 inside the info.json file of the mod should do the trick (at least it did for me). It's understandable if you want to wait for a stable version, though.
Thank you for your attention! As I said before, it's okay if you delay it or wait for a stable version (since 1.1 is still experimental), so take your time.
Also, I only know a thing or two about modding though, so I can't say I would be able to maintain one (and as such, I currently have none).
Oh, I'm sorry, I mistook you for someone else who's name starts with K. He's written a mod that encompasses the functionality in mine as well as the functionality in the progressive running mod. Kuxynator's Running Mod.
