This is a collection of code snippets for previously solved customization issues. They are supposed to go into your child theme’s functions.php or a subsequently included file (replace "child_" and "x.x.x" with your child theme prefix and version respectively). Putting them into the main theme would work, but will cause them to be deleted when you update.
Alternatively, you can put the code into a must-use plugin file. Create a new PHP file with a name of your choice in the the /wp-content/mu-plugins/ directory (create the directory if it does not exist). Use the following example code as base:

Related to this issue. Maybe you need a secondary chapter title to fulfill some arbitrary naming scheme; you do you. While not encouraged since this adds at least one new database row per chapter (plus another for each revision if you have not turned that off), which bears the danger of slowing down your site, this can be achieved by making use of an already existing meta field. Of course, you could also add a new one with more custom code.
First, check the Enabled advanced meta fields option under Fictioneer > General > Compatibility. This will, among other things, reveal the Short Title meta field in the chapter sidebar. This field is not actually used by the theme and only for customizations, such as this one. Just ignore the name if it does not fit, or go through the trouble of changing it.
The assumption here is that you want the normal title to be short, like "WTF 1", and the secondary title something longer. You could also reverse the order of things by changing the example code to match your requirements. The functions below will filter the titles for the chapter header and chapter lists as seen on story pages, but not on card grid shortcodes. Note that there is no styling for the secondary title provided, that is your responsibility.

Or change them completely, if you want even depending on the chapter or associated story. Related to this issue. Using a filter, you can rebuild the list item HTML to your liking. In the following example, the chapter prefix has been prepended (if there is one).

To prevent authors from entering a whole f***ing thesis of tags. This is not the best way, because it will just remove any tags exceeding the limit with no feedback for the author. But maybe that will teach them a lesson. Anything better needs to interfere with the Gutenberg editor and is difficult to achieve.
