Thanks for the suggestions! 0.1.23 (Factorio 2.0) / 0.2.23 (2.1) is out:
Direction: hold Alt and every sushi packer shows an arrow pointing the way items leave. Alt-mode also no longer shows the icons of the hidden parts inside a packer.
Buffer limit: each lane now holds at most one item stack of one kind (for example 100 iron plates or 50 ore). If the belt in front is blocked, one kind can no longer fill the whole lane; it is taken again once half a stack has left. Up to 5 kinds per lane are limited at the same time.
Fast sushi packer research: it already needs Logistics 2. In my tests (2.0 and 2.1, with and without Space Age) its prerequisites are Logistics 2, Sushi packer, Fast inserter and Advanced circuit. Electronics is only needed for the first (yellow) sushi packer, because its recipe uses a circuit. If your tech tree shows something else, please post your mod list and I'll look.
Also fixed: a packer with no belt behind or in front drew extra copies of its hood next to it.
1) and 2) works well now. Dont hard limit num of kinds. Big sushi belts in pY have alot of different items.
3) Fast sushi packer have dependency "advanced-circuit". But in pY it waaay later tech. Can you disable this dependency in pY? Or make startup option to disable all dependencies except sushi packers previous tiers.
There is no limit on the number of kinds. A lane takes any number of different items; with more kinds than the lane store has slots, the oldest leftovers leave early to make room. The "5" in my last reply is only about the new cap: the game lets a hidden inserter filter at most 5 kinds, so at most 5 kinds per lane can be held back at one stack at the same time. A 6th kind is still taken, just not held back at one stack.
Fixed. The packer looked up "which technology unlocks advanced circuits" before pY moved that recipe to Basic Electronics, so it kept pY's late Advanced Circuit technology as a dependency. It now looks after all mods have loaded. In full pY the Fast Sushi Packer now needs Logistics 2, Sushi Packer, Fast Inserter and Basic Electronics, so it comes right after the fast belt. No setting needed. The recipe still uses advanced circuits, but in pY you already have them by then: pY's own fast splitter needs them too.
