NewsLife's News Clipping sidebar is a great place to store articles you find while browsing your feeds. It makes articles quick to find again and prevents them from expiring after a certain time period has elapsed.
You can quickly add the article you're currently viewing to the sidebar by clicking the add button (1) at the bottom of the sidebar. If you click the add button while viewing a feed all the articles from that feed will get added.
You can also drag and drop article links into the sidebar.
The action menu button (2) gives you a range of useful shortcuts that let you do everything from email an article to someone to sending it to various online services.
To delete an article in the sidebar simply highlight it and press the icon with the trashcan icon (3).
If you're not using the sidebar or need to make some room on your screen you can always hide the sidebar by clicking the button in the top right corner of NewsLife's window. Just click it again to reopen the sidebar at anytime.
