Thank you for an excellent plugin; it does what it says!
EDIT: as of version 1.3.0, everything below does not apply anymore.
My only complaint (as of v1.2.1) is that it doesn't preserve the scroll/cursor position after saving the post. I think this is an important feature because the people who are using this plugin the most are those like me, who make frequent changes and tweaks, and constantly save/preview the updates. Having to find and scroll back to the last editing point is very frustrating and time consuming.
With the above feature, this plugin would be officially perfect!
