Actually, Mouse without Border is an app created by Microsoft; it’s an application wherein you could share your devices such as keyboard, mouse with other machines, and you can even drag and drop files between them using the same desk rather than using multiple sets of keyboards and mice which is awfully annoying.
There are a lot of things you can do with this App and it’s very powerful indeed, but since it’s from Microsoft, then it works only with Windows unlike its competitor Synergy which is a cross-platform. But even if it’s exclusive for Windows only, it’s very powerful and very simple to use since you can limit the number of mice on your desk. Check out the video for more info about this app.
