I do understand what you mean, actually most of the gtk3 porting work
has been made. Actually only those packages doesn't build with gtk3:

gpicview libfm pcmanfm lxmusic lxpanel

everything else builds and seems to work fine. i wonder if lxappearance
could be set up in a way that "if built with gtk2, i edit gtk2 configs,
if built with gtk3 i edit gtk3 configs" that way, we don't need to make
2 versions.
