[Announcements] Announcements: Lock to home

[joshua_cohen]

Certain announcements are critical to the classroom success and having them always present on the front page previews would be ideal to maintain their classroom visibility.  We’d like a checkbox option in the announcement settings that would allow for the instructor or admin to lock that announcement to the home page.  While the settings may allow for the 5 most recent to be shown on the front page, if an announcement was locked to the home, that announcement would be visible and then the other 4 most recent would be visible, regardless of the posting date.
