Options Screen Shots

General options allows basic configuration of Dinner Timer, including the default running time, time before the end when a warning should be raised, how long after the timer is complete that over run warnings should be raised and how long after the timer is complete that all notifier's should be stopped.

Opacity settings let you define how transparent Dinner Timer is during its various states, you can configure Dinner Timer to be practically invisible when stopped, be more visible when running and fully visible when the end point is reached.
Notifier's allows you to select which forms of notification you wish to receive when events occur.  e.g. If the bubble notifier is selected then the bubble notifier will receive events, this will then pop up bubbles to notify you as configured.
Notifier's can be configured from the Settings page and also from the main Settings menu.
Configuring the bubble notifier, here on the End Point event (when the timer is complete), we run the "Dinner Ready!" bubble once.
The Sound notifier can be configured to sound a built in sound or a custom wav file.
