With about 450 series in my tracker, it's quite painful right now to manage them through the "All" tab. The biggest pain point for me is not being able to easily ignore series I've already mentally cataloged one way or another. Being able to filter the All tab by a combination of user-based series status, especially Dropped, and additional series-based statuses would probably be sufficient.

Examples of filters I'd find useful:

• No (user) status
• In Progress & Currently Publishing
• Want to Read & (No Longer Publishing | Complete)
• Read & In Progress (to discover series that have unexpectedly received new entries)

Separating Dropped into its own tab (and not including it in All/by default) could also be nice.

Then Following could be explicitly about notifications.
