One new feature, a couple of fixes.
If you want to open a file you created previously, choose Open File from the Editor menu. Make changes, publish, everything should work.
Autosave is now more conservative, only saving after a second of idleness. So if you want to save, just let up on the keyboard as you type. In the upper right corner of the screen next to the version is a SAVED indicator. It flashes while MWE is saving.
There was a bug where blank lines would accumulate at the end of the document. This has been fixed.
