TL;DR
Make crafting machines that have quality (modules) have an output buffer for all qualities of items at the same time instead of one quality at a timeWhat?
Currently, if a crafting machine crafts an item of one quality, then crafts an item of a different quality without the 1st item being taken out - the 2nd item will not be able to be placed into the output slot, blocking further crafting until the 1st item is pulled out.Instead of that, items of different qualities should either go into completely separate slots or into some other kind of buffer to not block further crafting
Why?
This quirk combined with1. Very fast crafting time (>1 craft per tick)
2. Inserters having 1 tick of delay
Or even just
1. Fast crafting time
2. Inserters having downtime mid-swing
Significantly slows down crafting of quality items, which makes it hard to use the quality system outside slower recipes, which in turn makes it hard as a mod developer to use it for anything other than small scale crafting of base building supplies.
I think that with this change, the quality crafting system will become usable in more scenarios when developing mods.
