Second one is bigger though: why geany doesn't have any kind of Trac? It would be much easier to post bugs or feature requests there, instead of mailing list, and they would be much more visible.
Maybe not that big at all. There is a page on sourceforge about geany with tracker services and so on. You may want to have a look at this: http://sourceforge.net/projects/geany/
It is also possible to track bugs and feature requests there. I think this perfectly does the job trac also would do.
BTW: Just for those of the mailing-list readers who didn't know, there is also a project called geany-plugins on sourceforge:
http://sourceforge.net/projects/geany-plugins/
