I'd like a feature (built-in or else) that can parse HTML documents and iterate through any HTML tags that are missing respective closing tags.
A bonus functionality would be if it can also be aware (via doctype) whether to warn about self-closing tags or not.
Practical use case / workflow:
1. Hit designated shortcut.
2. Feature parses document and
3. For each case where a tag misses a closing tag, it stops at the opening tag.
Additionally, it would be like icing on the cake if it reports about results/progress on the status bar each time the shortcut is pressed.
