If the Quickbar is not enough, create toolbars that can hold items and tools and be positioned anywhere you like.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
Would it be possible to add the ability for the toolbars to hold a Signal value like the Checkmark? It would greatly speed up configuration of circuitry if I just had a bar on the side with all the signals I usually use.
I will think about it.
