chikutik reads your Google Calendar through its private iCal address. It can read events, not change them, and only you can see the address.

1. Open Google Calendar in the browser and go to Settings.
2. Under Settings for my calendars, pick the calendar.
3. In Integrate calendar, copy Secret address in iCal format.
4. Paste it below. Add as many calendars as you like.

Groups keep related projects together in the list and the filter. Leave it empty if you do not need one.

Renaming also updates every task, claim, link and snippet in this project.

Fields you leave empty stay as they are. Tags are added to the tags each photo already has.
