Don't forget to rate if you like it!
Step 1: Viewing
You obviously can't view without viewing.
Go to "Explore v" and click on one of the things that comes down in the dropdown, and pick whatever you are looking for.
Then move onto the next step when you are ready.
Step 2: Changing
Look at those two icons right before the words "sort by:".
There should be a list icon, and an icon with a whole bunch of squares.
The old one is the list, the new one is the squares.
Click the list icon to change it back to the original.
