I'm playing with the idea to build a service or add-on for Google Calendar that makes the use of templates possible in Google Calendar. The idea would be that you use the event title as a trigger. Like for example use "Tennis" as the title of you event and that the service automatically enriches/fills in all missing details like the location, duration, invite the people you always play Tennis with, etc... I like to be organised so this would really give me a clean and "correct" calendar. Is this something you or other people would use? PS: I know Fantastical has something like Event Templates but that only works with Fantastical. This would make it possible to use whatever client.
