Okay, just like to start this question by saying I love the OSX Mail App. I use it for both my Gmail and iCloud email accounts. The problem I have is my wife and I share the same Mac (no, we're not quite a '2-Mac' family just yet). At the moment we have all our accounts in the same place which is actually quite annoying sometimes, as notifications come through and we end up being interrupted with emails that aren't for the right person (my birthday surprise was also slightly ruined last week when I saw an email come through about organising a secret present for me!). Anyway, question is, what would people recommend as a great alternative app for Gmail? My wife has multiple accounts, all with Google (she's a very busy person, don't you know), so something that would cope with that would be great. Something that's not too lightweight, a bit more than just a simple inbox, but nothing too heavy duty. Thanks all!
