Allow expanding and collapsing of any and all tags on Subscriptions view

App version: 3.5.0 (300baf6dd) from Google Play

Desired Behavior: Allow the same expanding/collapsing as on the navigation drawer. Any and all tags should be expandable and collapsible to see a hierarchy of subscriptions under each tag.


Detailed description:
When subscriptions are tagged, they are collapsed/hidden one layer under the tag. These tags cannot be expanded on the Subscriptions view.
However, they can be expanded (and collapsed back) on the navigation drawer. like so:

  • News
    • NYT
    • WSJ
  • Comedy
    • No Such Thing As A Fish

On the subscriptions page, they appear as:

  • News
  • Comedy

If you set the tag for NYT as “Show this podcast in main list”, then on the subscriptions page, it looks like:

  • NYT
  • News
  • Comedy

And on the expanded drawer, it looks like:

  • NYT
  • News
    • NYT
    • WSJ
  • Comedy
    • No Such Thing As A Fish
