[Feature] Trackpad above Touch Bar on iPad #26

It will be great if you add virtual trackpad on free space in app for iPad.

As much as we would like to do this, there is no way on macOS to simulate trackpad input at the moment.

could this be of any help? Sorry if it's useless but I found this and thought maybe it would be useful.

@par5ul1 Just did a little research, seems its main propose is help you inject multi-touch event if you already got a OSX-supported multi-touch device - it means magic mouse/trackpad. For those who don't have either, the multitouch framework cannot even start working ( cannot get a valid MTDeviceRef - and all later works depends it ). To make it work, we'll need first emulate such a device, from driver level, to makes this framework thinks it exist to work; and then, all gestures still need be recognize by coding by hand - currently only 2 finger swipe/pan/rotate implemented - since seems the magic mouse/trackpad hardware recognize them internally. And the framework seems being rewritten by mavericks, possible more reverse engine needed. Seems its would be a much bigger task than the whole project currently.

Not to beat a dead horse, but could a subset of "non-pointer" gestures be more reasonable?

My (probably very personal) scenario: I use a mouse but still reach to the trackpad for two-finger scroll and three-finger swipe-between-spaces.

Even if that's going too far, thanks for publishing this! I hope it will drive TouchBar emulation across other "use my iPad as a peripheral" apps.
