Thanks this mod works nice =)
Early i used schall belt configuration mod - https://mods.factorio.com/mod/SchallBeltConfiguration
it was very very useful mod but it some broken and can't work with all modded loaders
With this mod all looks okey

One wish to belt speed customization - can you add option to change multiplier of speed for each type of belts - yellow + red + blue + green from SE - and may be some modded belts like this mod - https://mods.factorio.com/mod/berbcorp-belts - i looked into code and looks like for now it can work with vanilla belts

My wish consists in having speed of 3 vanilla belts speed in this form - yellow belt 30 iterms/s, red belt 60 iterms/s, blue belt 120 iterms/s - when i used schall belt configuration i could have those speeds - so for now i want to tune blue belt for 120 items/s

Glad the mod has been working nicely for your loaders!

I won't be adding individual per-tier settings directly into this mod. The whole reason it's clean and supports modded loaders is because it's strictly a single global multiplier. Adding per-tier sliders would defeat the main point of the mod.

However, I just pushed an update specifically to make it play nice with Double Speed Belts:

1. Update this mod to the latest version.
2. Install Double Speed Belts (this changes base belts to double each tier: 15 / 30 / 60).
3. Set the global multiplier in my mod to 2.0.

Because my mod now explicitly runs after that one, the math hits your exact target:
- Yellow: 15 × 2 = 30 items/s
- Red: 30 × 2 = 60 items/s
- Blue: 60 × 2 = 120 items/s

Give that a shot and let me know if it works for you!

Hmmm this way can work as crunch - with double speed
Don't want to offend you and this mod but schall belt configuration added best way to change belt speed - at least only vanilla belts - it was really handy
I'm not handling much at lua code, may be you can look at schall's code and this mod could be improved - more accurate tuning could be good

The feature you're asking for from Schall's mod is the exact reason his mod breaks loaders in the first place. I built this mod specifically to avoid that mess, to support as many other mods as possible.

The Double Speed Belts + Belt Speed Multiplier combo gets you the numbers you wanted, but beyond that, I won't be adding per-tier settings.

So we need separate QoL mod for tuning belts splitters underground belts (its length) and loaders - need to ask some one to make this mod
And mod to change length of pipes (include moded pipes) and pipeline extents
