Here are some of my favorite apps.
Mailbox by Orchestra. Oh this is a beauty. Set it up to handle all your gmail. When you get an email, you can chose to Archive, Delete, or Save for Later. Whatever you choose will be updated across all your platforms (phone, tablet, or computer).
Save for Later is awesome as it will let you take that email about where and when to drop off your child next Tuesday and set it to reappear in your inbox next Tuesday. You don't need to think about it until then, so why have it sitting in your inbox all weekend?
So, if an email is read-only, that is, no action on my part is required, I just read it and archive it. If action is required of me, I can deal with it immediately, or save it for later. Alas, it is not yet available for my desktop, but it is coming.
