I absolutely adore this app, I've used illustrator for +10 years and I honestly feel that manipulating beziers through direct input in Inkpad is not only a more pleasing, and intuitive, experience but in a lot of cases a more effective method of creating vector art. I frequently use it throughout my design process (and occasionally for the entirety of it).

You should be extremely proud of the powerful a tool you've created, and I hope that this transition to open source is positive for the app and for you and your team. I can't wait to contribute, even if it's only by way of design suggestions.

I'm pretty sure I've emailed you with glowing compliments before but I can't tell you enough how much I love using your app.

I'll post a few of my illustrations in the hope that other designers might see the potential of this tool and start using it too:

I assure you any perceived simplicity in my images are a product of my style rather than any limitations of the app :)
