Please allow for faster server change. No need to force user to first disconnect then reconnect. If I want to connect to a new server then disconnection is implied. Let the app handle the disconnect automatically when I request he new server so that I only interact with it once without waiting for the first step to complete.

Also allow server changes from the drop down menu bar (Mac) without opening the full app window.

See Tunnel Bear for how they handle this. It’s easy and seamless.
