I’ve tried it. There were three issues:

1. Mouse movement was pretty choppy. Not exactly a dealbreaker, but it took a little extra effort to aim at buttons.
2. There wasn’t an easy way to do keyboard shortcuts. I googled the issue and people were suggesting to change the system keyboard to one that includes extra keys like Windows, Ctrl, etc. I really didn’t want to deal with that.
3. The interface was pretty hard to navigate. In the absence of extra keyboard keys, I looked into creating a custom script in the app to maybe do things like Alt+tab a different way, and I never found it. Both apps said it had to be configured on the other device.
