Make dual monitors easier to understand what the pair of screenshots is.
Display them vertically only rather than horizontal then vertical
Take bigger, higher resolution screenshots at a 5-minute interval and then delete older ones over time.
-- They could be 50% bigger which still makes any text impossible to read but at least makes it easier to understand what's going on, especially at a glance
Take a screenshot more frequently when using unproductive or neutral apps and much less frequently for productive apps
-- Also allow filtering for screenshots of productive/neutral/unproductive apps.
Have the ability to flag screenshots to be saved
Have the ability to review all agents screenshots at once and then flag questionable screenshots for saving/further review later (definitely don't go through each employee one at a time.)
