There are a few shortcomings on the toolbar
1. There is only a pin/unpin mode. The toolbar often obscures a clickable portion of the hosting screen (minimize, close, etc.). The only way to work with it is to either move the underlying window, or unpin (hide) the toolbar from the top. Why can't it just be moved out of the way? The fixed location poses issues, especially when on a smaller screen accessing a host with a larger screen.
2. The tool bar should be customizable, adding the CTRL-ALT-DEL, copy and paste functions seems a lot more important and functional than the console and the two view manager buttons. If you ask around, I will bet the copy, paste, CTRL-AL-DEL are the most used functions and are difficult to access and I am equally sure that the fixed toolbar is problematic for more than just me.
3. The address book does not integrate with the mobile app, making the mobile app all but useless unless you've memorized all the internet ids of your PCs. Otherwise, how do you connect with a PC you have previously set up?
It is a great product, but it lacks some simple usability features which would make it easier to use and to sell.
