Next to the name of the announcement, you can see which feed the announcement is related to, its date status (eg. ACTIVE) 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
In addition, 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.
