Add and manage alarms and alarm lists with Cuckoo
Editing video clips, creating long documents, enjoying games, watching movies, etc, are sometimes part of our daily workflows, workflow tending to "use" numerous hours, sometimes more than we previously anticipated.
Usually, a remedy is the usage of an alarm that, set as one's initially scheduled activity, stops the in-progress activity after x hours/minutes.
Cuckoo is a simplistic yet effective alarm utility, aimed at setting and generating alarms in a matter of seconds.
Launching Cuckoo, presents the user a clear dialog with a properly categorized toolbar, from where alarms are to be added.

Clicking Add, summons a dialog, mainly containing a basic yet "enough" set of options, Audio and Alarm Time (featuring hours, minutes, AM, PM); alarms can be enabled/disabled via the ON/OFF button.
By default, alarms are notified via the desktop notification bubble, yet, the user can add to the notified-via-the-bubble-alarm a sound file by clicking Audio (action that opens a dialog from where a sound file is to be selected; Cuckoo comes with two alarm-specific sound tones, located under /opt-->extras.ubuntu.com-->cuckoo-->share-->cuckoo-->media-->sounds).
Editing an alarm is as easy as double-clicking on an alarm and adjusting the desired field values.
An interesting aspect of Cuckoo is its manner of dealing with multiple alarms, meaning, creating 4 alarms and navigating to Cuckoo-->File-->Save Alarm List (supported keyboard shortcut, Ctrl+S), saves the alarms as a list contained into a text file, later (after deleting the available alarms), importing (and thus adding/restoring the 4 previously-deleted alarms) is to be easily achieved by navigating to Cuckoo-->File-->Import Alarm List.
The handy alarm tool comes with an enhanced Unity launcher quicklist, exposing relevant actions at a press of a button, including Activate All Alarms and Deactivate All Alarms.
Appindicator's Show/Hide allows the user to hide (and show) Cuckoo's main window (where the alarms are displayed), presenting only its appindicator and removing from the desktop the window, while the app is running.
Along with the enhanced Unity quicklist and full HUD support, Cuckoo takes advantage of the Unity count badge, used to display the number of active and triggered/completed alarms.
Cuckoo 1.0.7 is available for free via Ubuntu Software Center.
Worth mentioning
Cuckoo has been created as part of Ubuntu App Showdown.
