(Yeah im cool suggesting things for stuff that have just been recently released)
Anyway, i just had the idea of adding these 2 simple upgrades for our machines:
Battery Input: Will allow to increase the Battery Tier our machine can handle, from Rechargeable Batterys > Energy Crystals > Lapotron. These upgrades are non stackable (Only 1 per slot), so if you want to go from Battery to Lapotron you need to use 2 spaces for it.
Storage Space (Input/Output): As the name implies, this upgrade will "Increase" or more like "Add" more storage for their respectives slots, Each Upgrade can be stacked to a maximum of 4 and will give 2 extra slots per upgrade. There also could be a mix upgrade that increase the slots from both input and output by 1 each per upgrade, maximum stack 4. (Maximum Storage per machine: 8 for input and 8 for output, extra upgrades will do nothing)
I may have more upgrades in mind, but im still waiting for Scumbag EE to update because i cant live without those alchemical bags QQ so i cant exactly play around with the new system.
