I have been iterating through the details of the designs for finding topics
on Flow (search, browse the ToC, and filtering). I updated this phabricator
ticket <https://phabricator.wikimedia.org/T76823> to provide an overview of
the related hi-level areas and link to the specific cards.
As tickets are considered for development, more details will be added and
cards will be split into smaller pieces, but for now I think the current
status provide a good overview of the main parts.
Please, feel free to provide feedback on the different cards (or correct
any Phabricator metadata I forgot to add).
