To add to that the W3C maintained the Amaya "browser", or web editor how they liked to call it, for like a decade and a half, as their vision for the web.

I think it was not just an appealing idea but Amaya itself was a solid implementation for a "testbed" (again, their words).

I can see why it died but I still think it is a bit of a shame it did.

I had never heard of Amaya before.

> It supports HTML 4.01, XHTML 1.0, XHTML Basic, XHTML 1.1, HTTP 1.1, MathML 2.0, many CSS 2 features, and SVG.

Perfect. Doesn't need anything else.

Amaya is great when you just need to do some quick edits.
