Header only toggles between h1 and h2

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Using the header button toggles between no formatting, h1 and h2 then
back to no formatting

What is the expected output? What do you see instead?
I would expect the headnigs to toggle to at least h3 (or at least be
configurable)

What version of the product are you using? On what operating system?
Latest version on Vista, Firefox

Please provide any additional information below.
This is maybe not a bug, possibly a feature request.  Sorry if this is in
the wrong place.
