I'm glad to hear things are moving along on this again. One thought, that I mentioned on another thread... Would it be possible to implement some sort of "pager" button? What I'm thinking of is being able to zoom in so you can write neatly, and then use the hand that isn't writing to scroll forward/carriage-return in steps, so that you wouldn't have to waste time scrolling with the stylus. I'm sure this isn't a priority, if it's even feasible, but I thought I'd throw it out there.
Well probably the whole canvas will be a pannable area and I will try to implement a similar feature: use the stylus and Xournal draws the stoke, use the finger and Xournal will pan around.
The device seems to report if you're using a Stylus or a finger, so I'll use it.
Of course one can switch back using the traditional method.
