I don't know if this would be out of the mod's scope or just too complicated, but it would be great if you could add an option to automatically request all item required by a certain crafting machine instead of having to select them one by one and inputting how many you want for each.
Example:
-> put down assembler for an item I want to craft just once
-> click button to create new request and select said assembler
-> it detects all items required for one craft (maybe open a dialog box to confirm selection, displaying items that will be requested?)
-> confirm and all items will be requested to the assembler

Is that something you'd want for just a single assembler, or like selecting multiple assemblers... In either case i'd probably put it into a separate mod if done.

I'd also be interested in this - I had been thinking about being able to ctrl-click on input slots to request the amount required for one craft per click (something I think vanilla should have had), but a selection tool would be significantly easier to implement.

The problem with the first issue is that ctrl+clicking it multiple times would just remove whatever items are inside the inputs and put them back into your inventory.

I'll add this as a separate mod idea, to request crafting ingredients from the logistic network.

I was thinking mostly about remote view, where there is no inventory to move items into, but you are right that another modifier (alt?) would be more generally useful.

None of the modifiers are generally recommended, alt will open factoriopedia, and both shift/ctrl will transfer items backwards. It will probably be a secondary button
