Hierarchy Bar

For some programming languages, it is very important to see a hierarchy of nested blocks/scopes and have the ability to navigate between parent and nested blocks. Especially, if nesting hierarchy is deep. For such cases, you can use Hierarchy Bar with its handy breadcrumb.

Check HTML source. Here you can navigate between BODY, TABLE, its rows (TR) and cells (TD) in one click.

And you can always navigate back to starting point. The same will work well for XML, for embedded languages or any other syntax. You can configure languages which need to have Hierarchy Bar enabled by default in syntax settings.
