The term 'Last Week' is erroneous - for most business people this will mean the last working week. In MSL it actually means the last 7 days (excluding today). There should be 'Last Week' and also 'This Week' with a setting somewhere to define the starting week day. Also the 'Custom Date' should persist for the session (or until changed). Currently I go in, set a Custom Date and as I navigate through my data and selections I suddenly see that the time frame has reverted back to my default. Not a good user experience.
