Feeds
On the left side you can see the list of feeds:
Click on the selected feed to view the announcements related to the feed. You can switch between feeds.
You can add a feed by clicking the "Add new feed" button on the top panel.
Next to the name of the feed you can see its location (Jira 
or Service Desk 
), place (e.g. Dialog 
, Flag 
, Full Screen 
etc.) and a little "abc" icon representing color scheme used in the feed.
Click > to see the number of announcements, edit or delete the feed, add an announcement and go to the Recorded Responses.
Announcements
On the right site you can see the list of announcements.
The default view shows all announcements.
Next to the name of the announcement, you can see which feed the announcement is related to, its date status (e.g. CURRENT) and edit and delete buttons.
To the left of the announcement's name you can see its type:
a) Simple text 
b) Single issue 
c) Multiple issue 
Additionally, the list of Feeds and Announcements works on the principle of "Drag & Drop", which means that you can change their location on the list.
In the case of list of announcements, this works only if you previously selected feed (the default view "All of announcements" is not enabled).
By default, newly created feeds and announcements appear at the end of the list.
