• A way to hilight which screen the mouse is on, even if with a hotkey. Beyond 4 screens, you start losing your mouse frequently.
• How does the connection-retry work? If it times out, is there a way to keep it from timing out? If it doesn't time out, is there a way to configure it to retry more frequently?

Features that are needed to make things clear for new users:

• More than one instance of the program shouldn't be allowed to be run at one time. (otherwise the config file gets corrupted)
• You should be able to run the configuration dialog within the main instance (otherwise it's VERY unintuitive, even to computer experts, how to prevent the configuration file from being corrupted)
