I have seven Gmail or Google Apps email accounts. I separate business, personal, etc. Within each email account, I organize my to-do items by label: Follow-up, Call, etc. I use smart mailboxes in OSX Mail to view my combined to-do items for each category. Sadly, iOS6 does not have smart mailboxes. My question: is there any workaround to this? I want to buy an iPad Mini, but only if it improves over my super old iPod Touch (second gen, I think) in being able to display all of my to-do items in a particular label, across all of my email addresses. If there is no way to get smart mailboxes or quasi smart mailboxes, is there maybe a way to use the new flagged smart mailbox and VIP smart mailbox to create the same effect? For example, can you have five different color flags (for my five main to-do labels)? (If so, do the flags sync with Gmail?) Or is there a mail app that has this functionality? Something like Sparrow (which I understand probably won't ever release an iPad app now that Google bought it)?
