Wouldn't it be better to drop the GTK2 UI for a Qt4/QML implementation that could be used in both Fremantle and Harmattan? You have Hildon QML Components in Fremantle, and there are even packages for Meego Qt Components that can be used with Harmattan applications. Obviously, it might be a lot of work and it's totally up to you. Thanks in any case.
There is a port of PyOtherSide to harmattan, because at least one of thp's apps uses it iirc.
me too, same option. Please dristribute the GTK stuff in openrepos. Very good idea and great help for N9 users.
