Unpopular opinion: Ditch everything GNOME, glib, vala, GTK and focus on making KDE, Qt, QML first class software. QML is powerful and is quite fast and can at least be made fast. KDE needs UI and design polish but the foundations are IMHO more sane than GNOME ever was. Move the good stuff from GNOME over to KDE. E.g. kio-slaves and gvfs should be one stable solid pluggable piece of software. And document that well - Good tools are already there - Qt is documented, QtCreator is usable, KDevelop is fine software - merge the efforts to make that platform fast and sane and secure. Also please stop that CADT stuff[1]. Won't happen, but one can dream.
First Qt would need to be written in C so it's usable from other languages. The list of broken Qt bindings is much longer than the list of working ones. That or the language bindings need to be part of Qt itself so they can be maintained instead of abandoned.
Qml is an awful xml+javascript layer on top of qt that adds nothing but unnecessary complication to building UI's. Using Qt directly is much simpler.
> QtCreator is usable
Funny, last time I tried it was literally unusable. The new project dialog expanded beyond the height of the screen and all I could do was kill the process.
Would agree to an degree, but KDE is adopting more and more Gnome-isms at the plumbing level as they do not have the deep pocket backing that Gnome has via Red Hat.
