The GNOME project at 15

And what I am also implying here is that not only were the existing concepts broken, but they were not replaced by anything that serves the same purpose better (and contrary to what you say, these things can actually be measured, as I explained many times before). The best Gnome developers can offer is occasional suggestions that are completely orthogonal to the problem - which is to use a different input device (keyboard).

PS. Sure, some folks have tried to minimise the carnage by providing extensions that bring back various things that were broken. However, extension are no more part of official Gnome than Firefox addons are part of official Firefox. They are certainly not part of the "official way" of doing things.
