Some of this is probably a bit repetitive, but stuff I'd like to see in the game:
- Show the cost of items before laying them down.
- I think a "left click action / right click cancel" approach would work well. I like the way Oxygen Not Included does it.
- Have a way to show the "tech tree."
- Maybe a bit more feedback as to why a robot is failing.
- Have a way to cancel construction of a building in progress.
EDIT: It would be nice to set a limit on general storage containers, so my bots aren't doing things like creating dozens of axes.
