Problem you may be having, or feature you want:
When you have many podcasts it is super helpful having ability to categorize/tag your subscriptions and then be able to filter by those - in Subscriptions, Episodes and Queue.
Suggested solution:
Add Category tag for Subscriptions that would then also propagate down to podcast episodes. It would be great to be able to add multiple categories/tags (e.g. one can decide to tag by language, by area etc.). Add then category/tag as a filter parameter.
