<div dir="ltr"><div>Hi,<br><br></div><div>Configuration is a good project area. I think 3b can consider some other options than GTK+ for the GUI also, for example wxWidgets can be made to work with Python from my quick reading about it, and there may be other options to consider. The choice of GUI should be made to maximize portability and also to best support the goals of Configuration. I'm not sure how drop-down menu-driven windowing GUIs would compare to some other approach in terms of usability and maintainability.<br>
