As I already wrote, I'm currently thinking of major rewrite of Wammu code. This is partly inspired by problems I have with wxPython, partly by with to change data handling a lot, what is needed for support for multiple phones and intelligent caching of it.
Today I started to add design notes to bug tracking system. Well it was mostly core dump of my brain inspired by questions one user had about future. All design notes are now publicly available and all of them are childs of bug #147.
These ideas are not yet definite and no code has been yet written (except of some proof of concept stuff), so you have great chance to influence Wammu future by reading and commenting them. I will also add there more stuff as most of my ideas is currenly on paper and I didn't transform everything into electronic format.
