Thanks for following us,
We now enabled a Bookmarks feature for all; it probably can make SA hobbyists easy to view your favorite posts.
Bookmarks feature is for posts only, it is simple and a bit different than Following feature (Custom your personal SA with "Follow" Feature | 使用“关注”功能构建你私人SA #1081)
You might try Bookmarks and Following feature to compare that.
How to use bookmarks feature?
If you are on PC, click the drop down menu ( down arrow of behind Reply button );
If you are on Mobile, Click the drop down menu on top-right;
Where to open my Bookmarks?
Same like Following Feature,
If you are on PC, you can see "Bookmarks" button on left side bar;
If you are on Mobile, you can click Top Bar, then select "Bookmarks"
