Any errors in this before I add to the MetadataManagement page? I'm mostly concerned about the titlepage_entries.
Code:
### Alternate Method for Series Descriptions
This requires Calibre 7.0 or later, which added [category notes](https://calibre-ebook.com/new-in/sixteen).
To begin with, go to Preferences > Add your own columns, and create a new column with a lookup name of `seriesdesc`, type of 'column, built from other columns', and a template of ``program: get_note('series', $series, '')``. You may also want to use 'Show with comments in book details.'
This will allow you to add a note to the series by right-clicking the entry in Book Details.
With 'Pass Calibre Columns into FanFicFare on Update/Overwrite' enabled, this allows the user to then insert the series description on the title page:
[defaults]
calibre_cust_seriesdesc_label:Series Description
titlepage_entries: seriesHTML,category,genre,language,characters,ships,status,datePublished,dateUpdated,dateCreated,rating,warnings,numChapters,numWords,publisher,calibre_cust_seriesdesc,description
Note that upon downloading a book from a series from the first time, you will need to add the series note and then run 'Update Always' to have it appear.
