It's not like having Inbox, but the interface is much more comfortable.

Thank you for the Firefox version ! <(^_^)>

Excellent solution to declutter Gmail web interface.

Great Add-on to decrease the bloat in GMail!
Good bye HTML view!

This addon brings simple, minimalist elegance back to gmail. The addon itself is small, and uses the bare minimum of permissions, which is great from a security perspective. The codebase is small enough to peruse in a few minutes.
