This is really problematic, since I been using Gmail + Apple Mail for basically...ever. I guess it's time to stop putting off moving to a more full featured client. Speaking of which, any recommendations for clients that feature a Mailbox-esque "remind" or "save for later" option? It looks like, of those linked in the story, only Mail Pilot offers one. However, their desktop client isn't yet available. Stock web-based Gmail is no good, since I have a ton of different addresses I use on the regular (no, they can't be unified, they're for different organizations), and the logging in/out is a huge pain. Plus I desperately need notifications, or I'll be even less organized with email than I already am.
