Hi, I have no idea why, but as it is, if this mod is started together with Maraxsis, then it affects the rocket capacities of items quite strongly - e.g. long-handed inserters now have a payload capacity of 12 stacks, normal inserters 16, red belts 3, etc. I have no idea why this happens and I'm not a Factorio modder, but I thought I'd let you know here.

--I fixed it in my side by adding Maraxsis as a dependency to ic-tweaks - I'm assuming if it's loaded after Maraxsis, it all works as expected.--

Update: I looked wrong - the dependency didn't fix it, my bad.

No setting should affect the capacity of the rocket.
I made a new version where it is possible to disable some settings (mostly the value -1 or 0, more in the configuration description)
