Hi, I'm a big fan of Across. I use it with an iPad Pro, even without a dedicated iPad client I find it meets all my needs. The only improvement I can recommend is implementing an option which prevents the mouse from shifting from the server to the client unless a condition is met, such as a time delay or a double-tap, in order to keep from accidentally switching devices when the mouse just brushes against a border. CRAP an open source client-server KVM tool, implements this as shown: I would think this would be possible to implement purely on the server.
