KDevelop is WM-independent -- its dependencies don't include the window manager or shell. This silo thinking has to stop. Basically all the library stacks on Linux have a shell project prominently associated with them (Qt/kdelibs: Plasma, GTK+: Gnome Shell, EFL: Enlightenment, Motif: CDE), so you run out of "WM-independent" apps pretty fast if you make that mistake. And considering Qt even calls into the GTK+ theming system if run in Gnome it strives to be interoperable more than most.

As for alternatives, I'm not aware of a Python IDE with comparable abilities for Linux (Wing probably comes closest, but is proprietary).

What has the potential for greater impact on your productivity - 320 MB of used disk space or a useful IDE?
