There's an update now:

Next step will be to make the feature suited for segments containing tags. Stay tuned.

Ready!!!

As a spin-off I'll create a macro ... that allows you to navigate directly to tags. How great would that be?

Or ... select all text between certain tags. Possibilities are endless :).
