I specify lots of question as my favorites without attention. Now my favorites become useless and unmanageable. I wish to find any way to delete them all and start to make as favorites with more attention for the next time in order to do a better search between them. So is there any way to undo favorites?
There is no "bulk" way of removing favorites, but there is a way which is somewhat easy.
Go to your favorites page, and click on the favorite icon of each question one by one. At least you won't have to go into the question's page each time.
