Hi Sundance

After the patch, it is a little easier. Here are a couple things you can try:

The patch added Z, X, C keys: Z to hide all agents or all army stacks. X to hide yours or AI (IIRC). C to hide castle.

Use arrow keys combine with mouse to scroll faster. You will be able to scroll faster when zoom in. If the distance is about half the map or less, you can try to zoom out to max, then use Z, X, C to hide things that get in your way.
