Marking a Question as a Favorite

Clicking on the heart to the left of a question will mark that question as a favorite.

To remove a question from the favorites, click on its heart again.

Questions that are marked as favorites can be easily found later by applying the Favorites Only filter. 

Marking a question as a favorite can be especially useful for hard-to-find questions or any questions you use frequently.

Favorite is a per-user setting. Marking a question as a favorite will not affect other users.
