I'm looking at Mac equivalent application "shortcat". While it technically relates to Unix & Linux, I think it would be a much better fit for Super User.
However, I was only able to flag as belonging on Meta U&L, or Stack Overflow. Can we add Super User to that list?
Edit: as pointed out by jasonwryan, there's Can the list of targets for "does not belong here" be expanded?.
Still, that was 2012, almost exactly a year ago. I'd be interested to take a look at the numbers again.
