The Gtk+ project finally gets a structured way to absorb voluntary efforts. Here is my proposal for a Volunteer Task List on gtk-devel-list. The task list is currently being constructed in the Gnome Wiki: GTK+ Volunteer Tasks.
In other news, there’s been some discussion on width-for-height and height-for-width management around Gtk+ recently. So I summarized the approach taken by Rapicorn, which in a nutshell allows arbitrary constrains with multiple resizing iterations and employs dedicated strategies to stabilize the resizing process: Hysteresis problems in Gtk+ – Rapicorn size negotiation.
