Usually I get several people a day telling me different things should be our top priority, and they're all different. When everything's a priority, nothing is. It's difficult to prioritise things, I wrote a bit about the considerations in the feature suggestions guidelines. There are dozens of things I'd love to do, we can't possibly do them all, and even the ones we do choose we can't have done instantly. It all takes a long time to develop and test, and every feature as a small long-term overhead of continued maintenance as well. So we have to be a bit ruthless about how we prioritise.
