I have been requesting this for some time now and haven't heard any response yet... I was hoping to get this ability in a future release.
Basically, I would like to be able to set the scale size per machine. I know that there are scale options in the machine properties however it is only 1/1, 1/2, 1/3, and 1/4... When I scale a connection I always use auto scale which is easily acheived by hitting CTRL+ALT+F10 after connecting. It would make it a bit easier to set it in the options so when you connect so it does this automatically. Either through the scale setting or the ability to set hotkeys per machine. Also another good Hotkey is CTRL+ALT+F4 (CTRL+ALT+DEL) to remote machine. So It would be nice to be able to do this one way or the other....
