Very interesting mod and great idea! I've been using Item network for quite a while but I stumbled upon some errors that the devs are struggling to fix. The other mod that you based this one upon I also tested to try to make my own version of C&C kinda sorta game in factorio but the suspended list on the screen used to not fit on my 19" screen and items got trimmed in half, so I only was able to see half the list. Where in Item Network, since its a scrollable list, I can read all the items available and their respective ammount.

Item network has an issue that I think you fixed on your mod, which is blueprinting chests. I think on yours from the small vid you can use a sort of tool to do the copy-paste part and, since you don't need inserters, should require less overall structures.

Another issue with Item Network is the fluid handling and throughput. Fluid requester operates like a regular tank but can only store 5k units of any fluid, you can't increase that. having it behave like a tank, essentially limits throughput to 1200 units/s when dumping it into a pipe, requiring a pump to fix that but, due to how the mod process the chests, takes a while to request another 5k fluids which tends to lead to starvation on bigger factories.

With Omnimods you can reduce that bottleneck a bit since it treats fluids as solids so you "unpack" the fluids when using them on machines, basically only need to "unpack" flamer ammo and steam for turbines. But as the factory grows, the timer before next request also increases.

Since you stated you haven't tested it on bigger factories, I could try it here and if you want, send you the save file for debugging, but I would really like the items to be shown in a list inside a scrollable window instead of fixed on top of the UI

Thanks!

I do think the item table GUI needs a rework: I was thinking of making it similar to the tabs that show up when you set an item request - but instead of being tabs, there would be buttons which let you rearrange/hide the item tables. The issue with this is that if the intermediates tab has a lot of items then the item table will still end up being massive. A scroll bar might help with this.

Fluid throughput should be pretty decent in my mod as each of the tanks are processed once per second - that's 25k/10k fluid input/output per second. You can always add more tanks if necessary, like this 40 GW nuclear reactor where the water and steam is managed by my mod: https://imgur.com/a/BZPy9mg

I am currently building a megabase using my mod to see where the performance lands. It seems to be quite good in its current state - though my target of 10k SPM is probably a bit small, I do wonder if 20k SPM is possible using solar instead of 256 nuclear reactors. Please do share your save if you do end up building something massive or something that has performance problems.

I should probably add a UI that shows you how many entities the mod is managing as well as how many it's processing per tick. Would be useful to show timers there as well.

I've found some issues, will post them in another topic so its easier for you to control them
