Would it be possible to add support for third party trackpads (like the Logitech T651) to BTT?
Unfortunately these do not offer any (official) way to access the sensor data, so it's not possible. I once requested this from Logitech, but they never replied. (Also they are worse than the Magic Trackpad 2, so I don't see any reason to further look into them - I have a T651 here and it's much worse than a Magic Trackpad 2)
I thought so, thank you so much for your reply, I really appreciate it
