The approach I have been taken with Surface Tweak Tool, is: better be safe than sorry. I don't like to blindly offer tweak option to something that I don't know the result and start breaking people devices. I don't want be "that tweak tool", that screws up people Windows or devices. So, if untested, the option is disabled.
If I have active testers , I can look into enabling and supporting these features. I can also look in supporting the pen calibration, potentially as well. And I also have another software in the burner that need testing. I would love to have one on one interaction with people that don't mind actively testing and making the software better.
If you are interested, or anyone else, private message me, and I'll start cooking something up.
Thanks in advance!
