Awesome stuff! I'm loving how these features are shaping up.
A few further suggestions on the aggregate view:
Like Threads and Microblog, All Content should have a number next to it (just the number of threads + the number of microblog posts).
I think the homepage setting should be split into "homepage feed" (all, subscriptions, moderated, or favorites) and "homepage view" (all content, threads, microblogs). That'd make the current dropdown a lot less cluttered.
It'd also be helpful to have a "default view" setting that applies when you go to any magazine or feed. For example, if I go to /m/Kurzgesagt and my default view is set to All Content, it'll start on the All Content view.
Should you keep the homepage setting as it is, there are a few issues with the dropdown:
When you select something, the only text that shows is the feed, not the view.
When you select something, the option that you currently have saved moves to the bottom of the dropdown.
Not sure if this has always been a thing, but the dropdown uses "Subscriptions" while the channel list in the header uses "Subscribed".
ETA: One more issue I forgot to mention — when you click All Content on the favorites, moderated, or subscribed feed, it sends you to the all feed.
