Re: [Xournal-devel] Chrome experiment

[Wouter G. <wou...@gm...>]

Hmmmm I disagree. I have pressure sensitivity shut down already at the
start. I find my handwriting much better to read with it turned off. The
main benefit for me is that Xournal can detect shapes I make. It is very
handy when it comes to drawing electrical circuits or drawing a diagram or
something. For that reason I also suggested the 'shape' library in one of
earlier e-mails.

Further HTC is proberbly going to release a tablet with a stylus.

I
heard there were plans on porting xournal to Android... Any progress on that
part? At the moment I started to reading the developer guide of android
because I got myself a new mobile with android and want to make a app for my
university.
