Is it possible to make myself a list of topics that I look at most?

[AtiaoftheJulii]

I mean, obviously I could make my own list/bookmarks, and I know one can hide topics that one doesn't want to see, but is there a way of collecting 'favourite' topics?

On the current App, Yes - you can set up My Topics - but I don't think there is on the other sites. (Happy to be corrected on that.) Bookmarking your favourites is probably as easy a way as any.
