Hi Caitlin. Did you see my post?
I would really appreciate any answer - positive or negative.
The reason I have an expectation to see a toolbar API soon is your blog post “Add-ons at the San Francisco All Hands Meeting”, where you wrote:
Additionally, we’ll be working towards supporting visual overlays (like notification bars, floating panels, popups, and toolbars) by the end of the year.
A toolbar API where also one of the planned APIs at the New WebExtensio APIs page at the wiki before it was removed.
If these plans are now of the table I would really like to know.
