On Scrolller you can browse files from the top subreddits of the web with a neat little browser. Now you can also open more than one subreddit in one tab at a time, and you can also browse other websites at the same time with the cool little extension that this extension adds. 

The app has its own little keyboard that adds a few shortcuts for browsing the website, and it also adds keyboard shortcuts for saving a file in the slideshow and for opening a new tab in a new window.
