Describe your enhancement

Add an inventory to either the crafting grid, or the network, where you can store workstations: smithing table, stonecutter, chipped workstations. Then, similar to the pattern grid, you will be able to switch between workstations for crafting, either manually, or automatically when you click in a recipe. If the workstation is not available, the ingredients will just be pulled into the crafting grid (the behaviour in RS1, but not RS2).

If I implement this, would you consider adding it to the release?

Yes, but it would be for after the initial few releases.

Of course

These are so niche, just switch the container if you need them. Or set up autocrafting.
