Review for GMail Labels by wilf21
Rated 4 out of 5 stars
I was looking for a way of seeing which Gmail labels are attached to an email and this seems to do the trick albeit with a delay when focusing on a particular email. It would be nice for the label colours to mirror those set in Gmail itself, but I'm assuming the labels are derived by looking into the IMAP folder structure rather than by getting anything directly from the Gmail server itself.
