This has two configurable options: one for how many tags you want to show on search page listings, and one for how many tags you want to show on the work itself when you click into it.
Default: const MAX_TAGS_ON_BROWSING_PAGE = 15;
The number includes all tags on a given work except title, author, and fandom; those appear even if you set this to max_tags = 0.
You can change the number to whatever you want. I have mine set reasonably high at the moment, so I don't have to scroll past giant blocks of tags all the time.
Default: const MAX_TAGS_ON_READING_PAGE = 0;
The number includes all tags in the header box on fanworks. The default 0 means that the header box effectively vanishes, leaving you with just the fanwork itself (which does include the title, author name, summary, and notes).
The script affects the entire header box as a unit. You can't set it for, say, 5 and have just the first five things in the header box appear. It's all or nothing.
If you want the header box to show up every time, set this number high, like triple-digits high. If something has more tags than the number, the box will not appear.
