I'm using the newest version of Gmail, as far as I know, and there used to be the option in Settings -> Labels that said "Show in IMAP" next to label/folder names. This option is no longer there, unfortunately. How do I hide specific labels/folders, e.g. All Mail, from Thunderbird, my IMAP client?
In both Firefox 17.0 and Chromium 20.0.1132.47 on Ubuntu 12.04, without an extensions, these options do not appear, so it doesn't appear to be a browser issue. In the past, I had to enable "Advanced IMAP Controls" in Settings -> Labs for the "Show in IMAP" controls to appear, but according to this post, those controls "graduated" and should appear under Settings- > Labels.
What can I do to show or hide specific folders in IMAP?
