Whenever Airmail syncs my e-mails and I'm in Inbox, I'm getting all e-mails first, then come the labels (little colored triangles attached to the list items). It's a bit weird to always wait a few minutes to get a "full sync" of my Inbox e-mails.
I'm always skeptical of archiving e-mails if they don't have labels attached, so I find myself always wondering whether the e-mails I just got in Inbox are labeled or not... and end up postponing archiving because of this. This kind of kills my initial productivity (when starting fresh and getting all e-mails).

I assume this is indeed a real issue given that people keep creating new requests with it :)
