I do not understand why v4.60+

I do not understand why v4.60+ was changed to be less convenient. I liked the efficiency of launch Mudfish client -> play. Now it is 1) launch Mudfish client, 2) click "Connect", 3) refresh, 4) play.

Actually, you don't have to refresh the display. You would already get connected to a Mudfish Node as you clicked as the Connect button. It's just refresh the display to show your applied status.
