Clear map feature

[HathewayWill]

Is your feature request related to a problem? Please describe. Unable to clear and reset the map when using projections or wanting to change from one projection to another

Describe the solution you'd like Say that I have a lambert projection but then I think that polar or lat-long would be better. I would like a way to clear and reset the whole domains and delete them to be remade.

Describe alternatives you've considered While the reset button works for sometimes it doesn't always erase the domains so you can start over fresh.
