Prof. Loraine could you please merge the pull request to the master?

link to the changed file in my app store fork is given below:

Could you please review the code again?

Prutha Kulkarni The Code Seems to be fine.

Working as expected, can be moved to Needs Testing.

To do functional review, you can add Prutha's fork to your local as another remote repository. Then, you can get the changes from her remote, feature branch as a "tracking branch" and deploy them locally for testing. Take a few minutes to learn this new workflow if you're not already familiar with it. It's a bit tricky, however. When I do this, I sometimes accidentally merge the other developers branch into my local clone's master branch.

For first level review, also please briefly say how you did the testing.

Please fix:
Next step in the workflow after First Level Review is moving the ticket into "Ready for Pull Request".
At that point, you re-assign to the original developer, who then submits a pull request.
When the pull request is submitted, the person who submitted the pull request moves it to the next lane in the board.
After the pull request gets merged, the person who merges the pull request moves it into the Needs Testing lane.

There is a bug: Categories are now all listed with one App only.
Returning to Prutha to investigate.

I investigated further. I think this is a correct – none of the categories is currently assigned to more than 1 App.
The site is behaving as expected and so I am moving this to Closed.
