Here's a partial list of what comes with this add-on:
- Add Row Highlights - eh, kinda cool
- Attachment Icons - pretty neat - displays icons for attachments in preview
- Folders4Gmail - this is the reason I got this add-on. works pretty nice. You just rename your folders like 'jug/jug sponsor' and 'jug sponsor' is a child of 'jug'. When you put labels on stuff it shows the 'jug/jug sponsor'. Kinda cheesy.
- Force Encrypted Connection (https) - eh
- Google Reader Integration - I haven't played with this yet
- Macros (? for help) - doesn't seem to work, I probably have to turn it on or do it right
- Show Message Details - ditto
