I like the whole project but have a Gaomon tablet unfortunately. This tablet has also some buttons etc. but cannot be configured with wacomtablet. Especially, my tablet is supported per the digimend project (http://digimend.github.io/). When I get it right, linuxwacom and digimend are *the* two big project for nearly all tablets. Maybe you can also support (to a certain degree) tablets from other vendors, especially digimend supported tablets?
