Developers: we don't feel like using GTK for new complex applications. We'd rather use Qt or ImGui or whatever. In fact, we'd rather create our own toolkit than use GTK.
GNOME: okay, here is our 5-years strategic plan, mostly about inclusivity and promotion of GNOME. Note how we are not addressing your concerns. Please send us feedback.
@prokoudine Yeah... The "GNOME Toolkit" 😛 is a dead end for non-GNOME software, especially cross-platform. Just fork it already and call it the "General Toolkit", or use something else.
@prokoudine To be fair, the GNOME Foundation doesn't handle anything in regard to the actual development direction.
