What you can find on this page:
Clear Local Storage
Choosing this option deletes all of your settings and data. This is the "nuclear option" and means you'll need to reconfigure your workflows and settings again the next time you use the tool. As of now, there is no notification once you've clicked on this link but the action has happened behind the scenes!
Color Scheme
You can choose to have a dark or light color scheme. See examples of each:
Light
Dark
