i have been playing with your mod a bit and using the green belts (1 tear up from blue express vanilla belts) and my items appear to move backwards? just my eyes or is the animation reversed? have used some red belts too and sometimes they also move backwards, but mostly the items stand still, probably moving too fast to see, lol.

anyways thanks for the mod, and using mini loaders mod too, but they are buggy or not working well for me, or i just cant get them to play nice sometimes. suggest if possible make your own loaders, or perhaps work with optera to get loaders redux to include loader compatibility with your belts, thanks again.

You are right, its an animation bug due to how fast the items are moving. I have a fix for the belt arrows, but I can't fix appearance of items on the belts.

As far as loaders go, 0.16 has issues with miniloader inserters. Factorio devs expressed disinterest in fixing it too :( see here: https://forums.factorio.com/viewtopic.php?f=58&t=58613&p=349267#p349267
I also have considered making some custom faster loaders, but haven't had the time to do it.

I'm glad you are able to get some good use from the mod! You've got an impressive setup going! Completely filling any tier of belt from Ultimate Belts is an accomplishment.
