The current icons-only notification system is generally ineffective to fully communicate different kind of system events. This feature provides a set of extensions to the current system to display simple text messages.

* Also, requires minimal extensions to jarabe.frame.frame(Frame) to extract the text information from the current notifications.
* Also, requires minimal extensions to jarabe.frame.frame(Frame) to extract the notification text message details.
* Plus, since the current notifications can't show up for long periods of time (to avoid visual spam) a new tray bar needs to be added to the frame.
* Plus, since the corner notifications icons can't be seen for long periods of time (to avoid visual spam), a new tray bar can be added to the left side of the bottom frame window. This tray will contain current session's notifications.

Running this python script should work (provided by Gonzalo Odiard):
<code><pre>
import dbus
BUS_NAME = 'org.freedesktop.Notifications'
OBJ_PATH = '/org/freedesktop/Notifications'
IFACE_NAME = 'org.freedesktop.Notifications'
bus = dbus.SessionBus()
notify_obj = bus.get_object(BUS_NAME,OBJ_PATH)
notifications = dbus.Interface(notify_obj,IFACE_NAME)
notifications.Notify("HelloWorld",0,'',"Summary","Body",[],{},-1)
</pre></code>
== Internet-Links in Notifications ==
*This would help in navigating to any internet-link, by simply clicking on the link.
*There are two cases possible ::
** No instance of "Browse" is open. In this case, following sequence of steps happen ::
*** User clicks on the link in the notification.
*** "Browse" opens (in a new window, obviously) and the URL is loaded.
** There is an instance of "Browse" already open. In this case,
*** User clicks on the link.
*** The window gets switched to the "Browse" window (if not already).
*** The URL is loaded.
*Code changes required at the client-side ::
**If the link needs to be added, with a particular text for the hyerlink, the following code needs to be written :
<code><pre> frame.add_message(body='Description', summary='First Title', link='http://www.linuxquestions.org', link_text='Click here to get answers to all your Linux questions')</pre></code>
**If no special text needs to be present for the link, we can skip the "link_text" attribute :
<code><pre> frame.add_message(body='Description',summary='Second Title',link='http://www.wikipedia.org')</pre></code>
