In summary, MarsEdit 2.1 has a new search feature, a new capsule-based tags editor, support for Movable Type tags, support for saving drafts to the server, massively improved preview performance and usability, and a bunch of other performance boosts and feature tweaks.
The first major update to MarsEdit since 2.0 came out last fall. I had the privilege to help with the beta testing and I’ll tell you that there are some great additions and improvements.
And if you’re wondering, yes I have a review coming out shortly.
