Collapsable folders in Navigation Drawer

[ghost]

An enchantment that would really help me would be the ability to collapse the feeds in a category so that only the category is shown. For some of my categories there are hundreds of feeds so scrolling to the category below can take a bit. I think having the ability to show just the top level folders (like it is in the web app) would be very useful.

Should be doable. The collapse/expand status of each category is saved server-side, so the subscriptions tree will have the same state on mobile and web.
