We're happy to announce our two latest features:

Instant autosave

Mockingbird now saves your project as soon as you make any changes to it!  This should be a big help to any of you who have experienced browser or computer crashes.  Additionally, we've built this feature to only send your changes to the server and not your entire project - so even if you have a very large project, the autosaves will be fast. And for those of you who like using Mockingbird offline (though this is probably not a great idea for long periods of time), you can still do so - Mockingbird will detect when you've gone offline and enable a manual save button for you.  When you get back online, simply click this button, and you'll begin autosaving again.  In fact, should the auto-save fail for any reason at all, Mockingbird will give you the option to save manually so you have no fear of losing any project data.

HTTPS access

Some of you have probably noticed that Mockingbird now defaults to using HTTP secure .  We spent some time running some benchmarks and found that there was no noticeable difference in Mockingbird performance by turning on SSL/TLS, and the security benefits of doing so are huge.  All your interactions with the site are now encrypted and transported over a secure channel, so you should have no fear of making the master mockup of your super stealth startup using Mockingbird.

Finally, a lot of people have been asking us about our post-beta plans, and we just wanted to give you a quick update.  We're currently putting the finishing touches on real-time collaboration, testing things as much as possible and deploying bits and pieces of it to production (instant autosave actually uses all the infrastructure for real-time collaboration, which is one reason we're extremely excited to have it released) and on our completely new account management system.  We've also been beefing things up on the backend, adding even more backup locations for your project data and building out a lot of monitoring tools to make sure that the new features we release are working well.  We really want to get these features out, but we hope the extra time and thought we're putting into them will show.

Hope you guys enjoy our latest additions, and as usual, let us know if you have any feedback or issues!
