These days I often have a hard time to keep up with the tasks on my TODO lists, but I do manage to sneak in a spare hour here or there to look into code I authored sometime ago and that’s waiting for maintenance attention. For projects like Gtk+/GLib it’s incredibly hard to figure a good start and order for bug processing if time is sparse and the number of bugs is flooding you.
Other projects on the net use issue trackers that support user voting of individual requests, here are two examples:
Of course I do realize that we have priority and severity fields in GNOME Bugzilla, but those are for a different purpose than polling the public opinion on which bugs should be fixed best/next, or which bugs have the largest pain impact on our user base.
At least for me, a publicly open voting system for GNOME Bugs would be immensely useful to judge where it’s best to concentrate my development efforts.
