First of all thank you for this mod which works with both trains and signals.
I know you are probably time restricted but would you be able to support slimmed down version of ultimate belts?
My mod with permission uses 'ultra-fast-belt' (speed 90) and 'extreme-fast-belt' (speed 135) without all the other belt versions.
Tech names are 'ultra-fast-logistics' and 'extreme-fast-logistics' without all the other techs.
it's basicly the same but only adds these 2 instead of all of them.

Hopefully its not a big ask, thanks again.
