I've seen the file transfer question before, but never one regarding windows. I would like to, without my internet-connected devices being physically connected in any way, be able to send specific program windows to the other devices.
For instance, when I need to head out, I could right click on my web browser's title bar and select Send To → Phone or Send To → Laptop, and everything I had open in the browser would now be open on the target device (assuming I had that same browser installed on the target device) and close on the source device.
Getting complicated, I might be editing an image and want to send that editor and my progress over to another computer.
My desktop/laptops are all Windows, and my phone is an Android. Are there any free pieces of software that do this?
