Make it so that powerful spam filters (like Spam Sieve level) are built into the mail client package and are cloud-based. While I love Spam Sieve, the fact that it is essentially desktop software chained to individual machines makes it incredibly sloppy. Any time you pick up and turn on your phone/tablet, thus breaking the chain of protection, spam leaks through. If there was a way to have spam protection as a service for email providers that don't already offer it (like Gmail does) that would be a great product indeed. I'd drop Mail/Sparrow and Spam Sieve if I could get it all in one package. That's my #1 gripe, less the prioritization and/or labeling of email and message types. Creating folders has worked pretty well so far. But I'd even be willing to change my workflow for an all-in-one solution.
