More Calendar Settings

It would be great if the calendar widget had more setting options.
For example:
- Option to start the week on either Sunday or Monday, not just Sunday.
- Option to show week numbers on left side of calendar.
- Option to strike through days that have already passed (ie. Track progress of the month)
- Create own colour palette (Like you can with font colour) - having a main colour, a secondary colour, and an accent colour or something. Would be nice to be able to customise the heading colours, etc.
- Option to change size, font, and colour of the "month text" at the top of the calendar.
- Option to lightly grey out the weekend day blocks, so that you can see the work week clearly.
- Option to change the way the "today block" is indicated on the calendar. I really don't like the dark grey fill of the today block. This could also link back to being able to create your own colour palette.
