1. My work week starts on Sunday, so I have:
(setq org-agenda-start-on-weekday 0)
Now the agenda timeline starts on Sunday as desired. However, it says on top "Week agenda (W34-W35)", i.e. it still thinks that the week starts on Monday. Can I change that?
2. It would be very useful for me if the weeks were numbered from the week when my big work project started. Can I have the week numbering customized to have W01 on a certain date?
