Maybe I'll have a look at it once I fiddle with my PC hardware and need to install a 64bit OS on a 40GB hard drive I have lying around. I very lately learned that you can switch to a classic start menu by right-clicking on the "K" start button. I consider the default tabbed start menu to be unusable and useless, thank you very much. Next I'll have to learn where to disable animations. Then, I don't know if I'll gain anything versus running Mate (which I use, with the Nemo file manager)
Mate is just too convenient for me, and not too heavy - it's gnome 2, and gnome 2 used to be heavy then computers caught up. My top panel is autohide, with stuff all moved around, and with CPU/RAM/Swap loads displayed right in the middle, CPU temp in top left, even real world weather. It doesn't look that good but those are very valuable features.
GNOME 3.6 well or more accurately GTK 3.6 introduced annoying bugs. Just open a GTK application with active spinner in an Gnome 3.6 environment. And see how this application eats your CPU resources. Under Gnome 3.4 on the other hand spinners don't increase CPU load remarkably.
Yes.. We can even feel concern about Gnome fucking up GTK3.
They can do whatever with Gnome itself, though when they decide to fuck up a new component that gives more work to the fork such as Cinnamon and the Solus OS guy ; but GTK itself is at a risk.. One small thing, even with GTK 3.4, when you have a "Open with" dialog, it defaults to a "Recently used" virtual folder instead of remembering the directory you last used, so you have to manually navigate to your place of interest. Just because they know better and we're not meant to know where to put our stuff in the file system hierarchy, instead everything has to be "dynamic" or "everything is a search" or whatever.
There were horror stories too about Gnome removing features in zenity for fuck's sake, the little tool that allows to pop up GUI windows in a script, and thus allows lay persons to use your little hacked together thing. They don't give a shit about breaking people's scripts.
I wonder if even GTK3 will get forked, or the major apps stay on GTK2 indefinitely, or migrate to Qt5 or something.
