HTML live previewBeta
Editing HTML in Editora just got a lot nicer. A floating browser-globe button
now appears at the top-right of any .html/.htm/.xhtml editor (mirroring the
Markdown preview toggle). Click it to open the current file in a detected
browser, Safari, Chrome, Firefox, Edge, or your system default.
The file is served over a tiny embedded web server bound to loopback only, so its sibling CSS, JS, and images load normally, and a small injected script reloads the page live as you type (it serves the buffer’s in-memory text, so you don’t even have to save).
It’s off by default; enable it under Settings → HTML Preview, then use the globe or the Open in Browser / Open in Browser… palette commands. No new dependency, it uses the JDK’s built-in HTTP server.
