I love Google Calendar, and have used it for both work and personal events for months. But it annoys me to have to click through multiple steps to import one of ICS files that Outlook uses to transmit appointments. Since I may have to add multiple entries during any given day, I wanted to speed this up. Thanks to GreaseMonkey and a couple hours on a Sunday (mostly relearning JS & DOM manipulation), I've sped this process up.
The cleverly named "Google Calendar Quick Import" script takes me right to the buried Import page. When I get the time/inclination, I will make this even quicker, but letting you upload the file directly ala the Quick Add popup. The other TODO I see right now is embedding the Import option into each individual Calendar.
Hope someone else finds this as useful as I do.
