Sorry for the delay in communication. I had some problems with my internet connection and was out of online reach.
In the meantime, I have been brushing up on D-Bus and improving my knowledge of Glib and GTK+.
Before I discuss more and begin my work on the proposal, I would like to know what module(s) can I contribute to for answering the question
" * Please include a link to the bug you fixed for the GNOME module your proposal is related to." ? Since this idea is not specific of a module, I am not sure what to do about it.
And although I haven't contributed to GNOME yet, I have contributed to Pidgin plugins and worked on a GTK based patch for it as well (under review..
https://developer.pidgin.im/ticket/926 ). So I'm quite familiar with open-source and GTK as well.
