Please do add this function from loosing users asap. Syncing flags is just a fundamental feature for every single email apps. There are a huge group of users who are used to flagging emails instead of moving them to an additional "starred" folder. I would suggest that DO NOT FORCE USERS TO ACCEPT YOUR RULES. It also happens that Airmail would automatically generate an "archive" folder while I never use the "archive" feature. I even couldn't delete it. In fact, Airmail can introduce another way to improve the efficiency by making a function optional. If I leave Airmail for iPhone, this would be the only reason.
