I’ve added another PR now that fixes the issue here Domain.com/bookmarks is showing domain.com/u/user/activity/bookmarks-with-reminders, and also adds the bookmarked post user avatar to the bookmarks list. It will be merged soon:
https://github.com/discourse/discourse/pull/9759
cc @Ellibereth , I know in an earlier post you mentioned you wanted to see the avatars, and @exetico for the URL change.
