RSS Sage-Like by arielg

Sage-Like is a simple, sidebar based feed reader (Atom, RSS, JSON and RDF). Like its add-on predecessors, Sage by Peter Andrews and the Sage++ by Higmmer, I did my best to keep it lightweight and fast.

  Pinterest and Behance.

 ● Fully customizable tree view. Add/Edit/Delete/Copy/Paste/Drag-n-drop directly
  in the sidebar.
