SDL Machine Translation Edge dialog

I just tried to use version 2.3.5 of the Edge plugin, and it is not working as intended. This may be because my VPN is particularly slow today. When I start typing in the server box, Studio more or less freezes. It looks like after each key press, a connection to the server is attempted, which of course fails since the name has not been fully entered yet. After waiting for a  few minutes, I could paste the server address in as a workaround. It then took me quite a while to figure out why the OK button remained grey. OK, the app description has a screen shot mentioning the extra return key press required, but it is not very intuitive, and we have to live with the fact that few people read release notes :-)  I know for sure I'm not the only one who fell for this trap.

Maybe some more UI changes would be in order?
