Possibility to temporarily hide a VAC

[mipastgt]

Is your feature request related to a problem? Please describe. There is currently no way to determine whether a VAC is correctly geo-referenced and shown on the map. It also may just hide some important information you are interested in.

Describe the solution you'd like I'd like to have the possibility to temporarily hide the VAC, e.g. via a button in the top-right corner of the screen, without otherwise changing the map display. See example: I'd like the VAC image to be replaced by a light grey rectangle outline of the VAC corner points.
