I'll post my issue via wiki.
I'm new to your app.
There is another issue; I'm not sure this a bug.
The undo feature doesn't seem to work in my tests.
In this example, as a test, once I've applied a header 3 to this text, I can't undo it—that is bring it back the way it was.
<p class="heada" xml:lang="en-us" xmlns:xml="http://www.w3.org/XML/1998/namespace">FOR THE BIRDS</p>
This is what I end up with; the text has lost its formatting and son on.
<p>FOR THE BIRDS</p>
