You may have seen the -n option which eliminates any confirmation, only selecting dependency SCEs or if there is not enough space when the size option is used.
I will look at this, but when answering confirmation, I check for a "y" and anything else is negative. To do the opposite, I would have to say that everything else besides "n" is a positive. Really not a big issue, as the answer is always yes and ctrl-c could stop the process at any time. Yeah, the enter button would be convenient as to not have to find the y button a few times during import.
Me, I use the -n option since I like as little interaction as possible.
