Does 'Next Up' behaviour not bother anyone else? Or am I missing something?

[bitmap]

The behavior you've described is somewhat present but in different areas.

* In progress weighted by last viewed

This is already how Continue Watching works unless I'm mistaken. You watch something, stop partially through viewing, that media takes first spot in this list.

* Next up from recently watched

Again, this is how Next Up works (most of the time). There are some weird edge cases where an episode fails to populate three list, but in general if you finish S01E05 of Series A, Next Up suggests Series A S01E05.

* Newly released episodes

These do not show up in the Next Up section. Newly released media show up in Latest sections for the library that they belong to. So this might be why a lot of folks seem satisfied (or at least content) with how things exist, because all of the functionally you mentioned exists. Next Up will have your next episodes for what you've been watching already, Latest will have the most recently released episodes. That's not a panacea, as Latest will contain the most recently added media, which could be released or it could be a series you added or old episodes you found.

If you're hoping for a new home section type or customized functionally, you'll probably want to submit a feature request.
