I would really like the option of being able to insert machine upgrades via a shift-right click in a similar style to the Factorization Barrel and Router Upgrades.
The reason? At current moment inserting upgrades into a machine seems a little inconvenient, as least to me. The inconvenience being having to open the GUI of the machine then dragging in the upgrades. So why can't we eliminate the middle man? The player would still have to divvy up the upgrades in their inventory, then they can shift-right click to insert all of the upgrades they have in their hand into the machine.
As for removing the upgrades, the player would still have to go into the machine GUI to retrieve them.
Thanks for your time.
