SUMMARY Some tablets, such as huion ones, in the left-hand mode mirror the screen (so that the connector is not in between the tablet and your arm) but not pen input. This last thing is done manually by checking an option in the software (by rotating the input by 180°). In the official windows huion drivers and in OpenTabletDriver the feature to rotate the input is present, but in KDE is not. This makes the tablet unusable by left-handed people. Please add the option to also rotate the pen input!
