 This file deals with the UI part (gnt) of the application
+TODO:
+- Allow showing feeds of only selected 'category' and/or 'priority'. A different
+window should be used to change such filtering.
+- Display details of each item in its own window.
+- Add search capability, and allow searching only in title/body. Also allow
+filtering in the search results.
+- Show the data and time for feed items (probably in a separate column .. perhaps not)
+- Have a simple way to add a feed.
+- Allow renaming a feed.
