While you are on the site, in your browser find and click "Add to Home Screen" A CGN beaver app icon will then be created to your phone that is directly link to the site.
Note: This feature may not be available in some browsers.
You can also create separate folders in your subscription section, to keep EE threads separate from everything else. I have a 'Watched EE Threads' folder. Under 'My Subscriptions', click on 'Edit Folders', and add a new one from there.
