Color is set to Very Low (8 colours) - I would suggest low (64 colours) or Medium (256)
Non of the followin input properties are set:
Send pointer events to server
Send keyboard events to server
Send clipboard changes to server
Accept clipboard changes from server
The first 2 are the worst - you cannot control the remote desktop with the default settings.
Besides changing the default values for new connections, it would be nice if the interface was extended with a dialog for changing the settings.
