As a Builder I would like all filters that use "week" (is during the current week, is during the past week) to start on Monday instead of Sunday.
Use Case: Our business calendars work on a sales cycle that is Monday-Sunday so having the "is during the current week" also include Sunday doesn't allow us to use these pre-set filters. I means that we need to set up more complex filters to handle these sales summaries.
I have a similar requirement, though more related to the date selection dialogue. Currently days/dates are listed from Sunday - Saturday across the dialogue, however we work on a Monday - Sunday 'week'.
