While editing in AST, the tested page has numerous highights and popups explaining the test (as seen in the screen shot. There is no way to turn that on and off.
There are times where the tester will need to use Snagit or other tool to capture a portion of the page in order to show the correct information in the screen shot (often times it has to do with an element outside of the DIV that is flagged, such as a redundant link or other element). Without a way to disable the highlighting, the tester is required to close the baseline testing to capture.
Add a button to toggle on and off the page highlighting.
