Not sure if this feature already exist, but it would interesting to be able to monitor and track my visitors/viewers.
At least being able to use Google Analytics in connection with the Cookie-Banner.
At the moment my viewers have allow cookies and then Google Analytics is started, not before. And most of my visitors do not allow = Google Analytics doesn't work too.
We don't have a built-in analytics but you can use Google Analytics to monitor traffic. More details here:
A Ticker for each gallery so that you can see how many views each gallery has had.
