This is a feature that no one else has, but it would be amazing. It's called "folder assignment". So here's the principle, you know how when you get an email it goes into the inbox and then you sort it right? Well you would be able to assign email based on the address it came from to a specific folder, so that every time it came from that address after the first time it would automatically go to that folder directly, and then on your screen you could just look at the number next to the folder to see how many new emails it had. Much better, much simpler, and much less work.
