I'm definitely planning on an hour-glass. I want to add this to some select functions (booleans, fillets, shell) hopefully for the next beta, also including the possibility to cancel out.

Eventually I want to figure out some type of feedback area where I could print a couple of lines of text for error and information messages. That's definitely one benefit of a command-line interface that it gives a natural place to print out that type of information. But it will take some fussing and experimenting to figure out how to integrate this nicely into the MoI UI, I don't think that I will be ready to do this part for a while.
