I've finally taken the time to connect my Sensel Morph tablet to my Windows 7 Professional laptop to try out the overlay functionality. I have an art overlay and have been starting to use Krita, so I figured I'd check out support.

According to their support page, their art interface implements Windows Ink. Crud - Krita doesn't support Ink . But wait - the 4.0 pre-alpha has Ink testing support! But it says that Windows 7 doesn't have support for the API. I decided to download it anyway... Microsoft does say that Windows 7 (other than Starter and Home editions) has Ink support. Now that I've connected a tablet that supports Ink I appear to have the various Ink tools like TabTip. And Corel Painter 2018 (Trial) definitely accepts my tablet's Pressure, Tilt, and Bearing once I turn on RTS tablet support and set up the brushes...

Unfortunately, I don't have the option to turn on the Experimental Windows 8 + Pointer Input in the tablet section of the pre-alpha, so I can't test the extended functionality against the tablet. Is this a simple matter of having disabled the option because it's Windows 7? Or is the implementation something other than the Ink API?

There are several api's that go under the name of Windows Ink, and the one Krita uses really only exists on Windows 8 and up.

Eventually I gave up and downloaded the latest (17.10) Ubuntu Studio and installed it to a USB stick. Lo and behold, Linux presents the Sensel Morph with Art Overlay (and No Overlay in art/brush mode) as a fully functional graphics tablet. Pressure and size work out of the box; I haven't tried brush orientation yet, but imagine it's there as well. The tablet should also work on MacOS, as the Sensel team actually delayed shipping their Kickstarter rewards when a MacOS upgrade broke operation with the previous built-in USB HID graphics tablet driver.

I did spend a bit of time trying to get hidapi compiled on my Windows 7 box, with the idea of adding yet another Windows tablet driver to Krita. It's easy enough until you want to use the GUI HID explorer program that you supposedly can make against Fox Toolkit; then you run into library conflicts and Visual Studio 2017 incompatabilities, and... I'll likely come back to it some year just because I'd love to have Windows support for the tablet, but it's work, and I have too many hobby projects already.

Is there some way to add the tablet to the supported graphics tablet documentation with these notes?
