Oh, I forgot to blog. Today I also started coding a little download manager for GNOME. It's much inspired by D4X, but uses more GNOME platform features (GConf, GnomeVFS, also freedesktop's D-BUS) and tries to follow the HIG. For file transferring, I'm planning to use libCurl. It's written in Python, which I don't know much, but already like it. Currently, only some UI work are done, you can see the first screenshot here.
