Very interesting document - hope this does lead to continued development. I'd be happy to contribute financially, especially for Javascript work, if that would help. Perhaps a scheme like Martin Wuerthner's for Gutenprint would be worth considering?
I'd also be interested to know if the GTK port has led to more coders working on the outstanding issues. I assume that the GUI and rendering elements are largely separate, so that changes made for the Linux versions could be taken advantage of by the RISC OS one.
Anyway, this is more good news from NetSurf, and thanks to all for the hard work on 1.0
