Selective Activity Timeline Display

With all of the activity that comes in the timeline, it would be nice to be able to select two or more tabs concurrently instead of it being "one or all". I'd suggest that if there was a check box at the top of each tab (Comments, Sent/Received, Opened, Clicked, Calls, Text, Direct Mail and Website Activity) so that you could say check "Comments" and "Calls" and have these display in date descending order.
