Adjustable Multi-week Calendar Display

I would like to see a muli-week calendar with only 4 weeks. The six weeks shown on the month calendar is too much. An ideal layout for me would be the previous week on the first row, the current week on the second row follows by the next two weeks. The old Mozilla Sunbird calendar had something like this. It was great. Of course other folks will want something slightly different, so a way to adjust the number preceding and following weeks from the current week would be better. Just as long as you don’t have to reset by hand each time you use the calendar.

P.S. This is great program.
