New in Sage 1.3: Live Bookmarks IntegrationSage now interprets Live Bookmarks just as it does regular bookmarks, allowing the user to subscribe to feeds using the auto-discovery mechanism ['auto discovery' bcs displays orange feed indicator in address bar when a feed is available -?] in Firefox. Live Bookmarks may be added to your Sage Feeds folder using Firefox's orange feed indicator icon, making them available for reading in the Sage sidebar. This gives users a quick and easy subscription method, while Sage's built-in 'Discover Feeds' function provides a more thorough scan. oh nice - when click on orange feed indicator and bookmark box comes up, can select (instead of bookmarks toolbar folder) Sage Feeds. sweet & easy.

Feed Item Toolbar and Mark Read/UnreadSage now supports marking feed items as read or unread. To do this you can either use the feed item context menu or the Feed Item List Toolbar. The following keyboard shortcuts are available (As usual you can hold down shift or ctrl when clicking the feed item to open it a new window or tab):
M ---Toggles the read state of the selected feed item
Ctrl+Shift+C ---Marks all feed items as read.
Enter ---Open selected feed item in current tab/window
Shift+Enter ---Open selected feed item in a new window
Ctrl+Enter ---Open selected feed item in a new tab
