Hello,
Leveraging the Anki Connect API, I came up with several Python Scripts that I found helpful for my daily learning workflow:

Most important, the script anki_export.py allows conversion of existing decks or tag-structures into HTML-format. In addition there are command-line navigators for displaying tag- and deck-hierarchies.
The script tag_to_deck.py converts a given multi-level-tag into a new deck, thereby preserving hierarchy-levels within the new deck structure.
Maybe some people here will find this also useful!
