Hello, developers and maintainers of Sunshine and Moonlight. I accidentally discovered these two streaming software and found them very useful during use. Thank you again to all the developers and maintainers. However, when using these two software, I found that Moonlight cannot correctly map wacom Pen Tablets and ugee pen displays to Sunshine, while Microsoft Remote Desktop can be mapped and used normally. If Sunshine and Moonlight add this support, it will provide great help for remote work and entertainment. So, can developers please add this support?
