All right, you can now go to "Edit -> Connect Stylus". Try reloading if you don't see it. I pray that it works for you. It's still somewhat experimental. :)
Sorry, forgot to clarify. WebHID is a way to get pressure sensitivity on Linux. It was tested on Wacom One and Intuos Pro. But may work on more tablets.
We have an experimental WebHID support for some Wacom tablets. Can you let me know your username? I can enable WebHID for you and will leave you some instructions on how to try it out.
We actually have it on the roadmap. Not sure if it will be a file export but imagine being able to share your drawing as GIF timelapse, or being able to go back to any point in your drawing or generate a video from the entire process. Or even use your own drawing flow as a virtual drawing partner.
We actually have 3 co-founders. Radek built aggie.io - it's been online for a few years. He initially built it to draw with his friends from South America. ;) First-hand need for art collaboration hehe.
Wojtek and I were in the meantime building code2flow.com, collaboration solution for diagrams. Also took us a few years.
2 years ago we decided to join forces and built an ultimate art collaboration solution with the experience and codebases from Aggie.io and code2flow.com.
Hard to say how many years ... Definitely over ten thousand of engineering hours but at the same time things were a bit harder few years ago when it comes to browser APIs so if we decided to rebuild it today it could take less time but we would also be more experienced.
Today we're hiring some more people and it's a team effort!
Thank you so much. :) Yes a lot of development went into it so that drawing experience is top notch. We're now expanding in areas that make it useful for a real production workflow. Game dev seems to be a sweet spot. I've been to GDC and spoke to a lot of people and got really good feedback.
