I have a few pdf viewer windows (instances) minimized in the dock. When I click on the viewer icon I want to open the one I used last. (Sometimes I minimize a window just for a second to do some quick action on some other app). However, clicking on a deck icon never opens the latest instance. Instead it always opens the first instance, (something which I didn't look at in hours), which just doesn't make sense. How can I change that?
The same problem appears to multiple instances in other apps.
