Actually this is 3.7.5.1 version that released today. This release brings mostly improvements in Network and Color sections, plus various enhancements in Sharing Panel.
GNOME users will take advance of the many new options in Settings, but they will also gains benefits from the better integration of Apps with the System. In short, you can do your work faster!
Easy of Use
GNOME 3.7.5 -so far- comes with 21 panels instead of 18 in GNOME 3.6 and many many new options. What is worth to be mentioned is the good work of GNOME Design Team to provide a really easy to use Settings and adjust your system. All features are discoverable at first sight but I have some complains because some options aren’t clear understandable what they do, and you might need to open the help -which by the way has hugely improved.
I won’t say that this is a completed Settings Center and for sure many things are missing, like the fonts configuration or the Firewall Setup. G-C-C 3.8 is now also closing a ridiculous bug; You can now switch layouts easily without the need of Gnome Tweak Tool.
Yeap. you now can cycle between layouts with <Super+Space> and also with an impressive way! If you have more than 3 layouts, Shell Info will help a lot as you can pick your layout also with the mouse! Nice one!
Notifications
I noticed a this small bug in design here. In Notifications Panel I currently have 7 Apps. With the 3.8 release they will become more than a dozen. What If I want to disable/enable the Sound or the Banner Details for all of them? Do I have to check them one by one? There isn’t a general Set.
If you find out such small details that bothers you, you can file a bug in Gnome Bugzilla.
Network Panel
Most of the improvements in 3.7.5 touched the Network Panel. Unfortunately I don’t have a wireless to test it.
The “Options” text button has now been replaced by the Gear Button. The Gear Button has also land in many other GNOME 3 Apps, like Disks. I personally like that practice as long as it remains clear what Options you will find there, and isn’t a “Joker (cards)” button.
The new Design for adding the networks details is pretty and clean. Also there is a new option here to reset or forget network settings like passwords.
The Egg Lists (?) came also in Network. These are just 4 huge buttons. It is a bit strange to see such thing in GNOME, but I +1 it. The cursor on them currently remains arrow.
GNOME Control Center Changelogs
GNOME 3.8 will be a huge improvement over 3.6, and I also listen very good things are happening in Ubuntu Unity. Both Systems are releasing pretty much the same dates and you can get them with Ubuntu and Ubuntu Gnome Remix -or any other distro you prefer anyway! The point is that Open Source Desktops give really quality choices to people!
