We now have the Annotation feature on the result page. I use this for documentation of changes in the test for external factors like marketing events. Often, I want to see the impact of these changes on the test. It would be nice, if we could select the annotion dates for start/end date in the Date Range selector. Right now, I have to this manually, which is quite painful.
In addition, it would be nice if the interface could remember my Data Range selection (via query string or custom view).
