I’ve been working on adding support to add users to groups in Tunnelgram.com. It won’t be out in time for Christmas, but hopefully soon.
If you haven’t checked out Krita, it’s an open source drawing and photo manipulation program. I just got the Dell pen for my XPS 9575, and with Manjaro Linux, it works out of the box! I gotta say, after having used art programs for almost a decade on Windows, I’m really impressed with the pen support of Krita on Linux. Even tilt sensing worked with no setup!
Anyway, Happy Winter Time Gift Giving Holiday!
