TL;DRI would love to see buttons in assembler interface that allow for more manageable transfer of resources for crafting, depending on the quantity desired.
What ?Buttons would transfer resources from player's inventory to assembler in exact quantity needed. For example Electronic Circuit:
+1 - would transfer - 3 copper cables + 1 Iron Plate
+5 - would transfer - 15 copper cables + 5 Iron Plate
+10 - would transfer - 30 copper cables + 10 Iron Plate
max - would transfer - 198 copper cables + 66 Iron Plate
clicking any button in succession would add up.
Why ?Currently the only way to transfer items into assemblers is with ctrl LMB/RMB on item or empty inventory space,
so for example if you want to craft 1 item you need to ctrl+LMB on empty inventory slot and then quickly ctrl+LMB on any item in the assembler input.
Also, if you want max Electronic Circuit from 1 assembler you will ctrl+LMB, and than RMB on plates to remove 50 and then add manually 16 extra, or leave those extra plates in the assembler until you pick it up or change the recipe.
Those buttons would make it much easier and probably will not bother anyone who do not need them.
