Unlimited weeks in Google Calendar

A Chrome extension to show more than 4 weeks in Google Calendar.

Adds + and - buttons to display as many weeks as your screen can handle.

How this extension works:

• wait for the toolbar to be visible
• add 2 extra buttons to it
• restore the main calendar's number of weeks, if custom view is active
• these new buttons adjust the number of weeks:
  • ensure custom view is active
  • using the navigation calendar, do a double manoeuvre:
    • click next month repeatedly during a click drag over the mini calendar
    • this is how we reach more than one month
  • ensure the calendar is still on the original start date
• use browser storage to persist the number of weeks selected
