Time is your most valuable asset.
Awareness is a google calendar gadget that provides insight and awareness into the time you spend and plan to spend so that you can maximize how you use your time.
The gadget would call on the google calendar API for the user's calendar event info. You need to index the every event description for the pound sign symbol "#" and record event start and end time information.
Then you would store that information in an array and visualize the data in the gadget - preferably with the google visualization API (https://developers.google.com/chart/interactive/docs/reference#GadgetHelper)
Here are the mockups I have created for the gadget - https://docs.google.com/presentation/d/1Q8lkvh0zE-7NW4cNR6npEu4KIwMupMtZpkY7Iu987x8/edit#slide=id.g295e4b1e4_118
API - Google Oauth
API - Google Calendar
API - Google Visualization (or other visualiztion library is fine)
