Currently we can filter out books in series when looking at our TBR. I think some useful related series functions would include:

• Filtering only books in series
• Filtering “up next” books in series in our TBR, potentially with a breakdown of if they are new series (book one counting as the next book) or series in progress
• Maybe adding series to the stats page, both in terms of in series vs standalone as a stat, as well as maybe allowing users to see stats for a series, similar to how we can for our tags.
