Full screen without keyboard and mouse

Here's the best workaround I've been able to come up with j-sind 

You should be able to activate the touchpad and leave it active. To get it 90% out of the way, you can drag it of the screen in the lower right corner leaving just enough of it visible to drag it back onto the screen when you need a mouse.

This should work well in conjunction with the unsafe:edge://flags/#edge-enable-shy-ui flag as well. 

I guess this is the best solution we're going to get from Microsoft. They should at least document it, since it seems they have no interest in fixing the underlying problem they've created. 

Here's a demo https://youtu.be/oTiMV6VVpmM 

I'm using Canary in this video, and for some of the actions I used a real mouse (hence the pointer), but only to facilitate the screen recording.
