Google has a feature I never use named Google Dictionary. In the Google Dictionary, users can "star" words to be put in a special list for later.
Earlier this week, the starring feature stopped working. A thread was created at Google Web Search Help to report the issue. Days later, Googler Emmit confirmed the bug and said they will look into it. Emmit said:
Hi all, thanks for reporting this and sorry for being a little late to the party. This issue is being investigated, and I'll circle back when it's fixed.
It's great to be reminded how useful Dictionary and its features are to our users!
Hours after that message from Emmit, the bug was fixed.
Here are some pictures of the starring feature:
I should note that there is still a minor bug in this staring feature. The stars don't stay on when you go back to that word. By that I mean, if you star a word, and then search for that word again, the star is white, and not highlighted yellow.
