Hello Café, I would like to propose making haddock keep instance lists collapsed by default. Some discussion is in order since it would significantly affect the documentation of many packages on Hackage. Feel free to reply here or on the related Github thread: https://github.com/haskell/haddock/issues/698 1. Instance lists take a lot of screen estate For a motivating example, I can point to the Prelude we all love. https://hackage.haskell.org/package/base-4.12.0.0/docs/Prelude.html We are immediately welcomed by half a page of instances of Bool, which is not quite bad, but classes have the most impressive instance lists, as you may see when you reach Eq. Many packages, even commonly used ones, have the same issue. For an extreme example, see the scrollbar jump when you fold the instance list of Apply in singletons. https://hackage.haskell.org/package/singletons-2.5.1/docs/Data-Singletons.ht... 2. Current workarounds They can be collapsed manually one by one, and we can jump to the middle of a module with the table of contents, but scrolling up from the bottom of an instance list is still a chore. Of course, instance lists also contain quite important information. Would it become too easy to miss if it were hidden by default? Would a more fine-grained alternative be better? Regards, Li-yao
