Suggestion: The current interface for crude data storage is kind of clunky/unintuitive. I was eventually able to find out how to use them by digging through the change logs, but for a while I just assumed that they weren't implemented yet.
I think that one possible alternative way to use the data storage would be to left- (or right-) click on an inactive bot to open up a screen similar to the bot teaching screen, but with a second panel on the right showing the program stored on the disk, and two buttons to save to and load from the disk. (The buttons could either be "save"/"load" or stylized `->`/`<-` buttons.)
