One thing that I like to do is peruse the installed applications on any computer system. In most cases, this is simple enough to do but there are some who appear to believe in doing away with that in favour of text box searching. It also seems that the GNOME have fallen into that trap with version 3.8 of GNOME Shell. You could add the Applications Menu extension that is formally part of the GNOME Shell Classic interface and I have done this too. However, that has been known to freeze the desktop session so I am not that big a big fan of it.
However, there is a setting that brings back those application categories in the overview screen and it can be set using dconf-editor. After opening up the application, navigate to org > gnome > shell using the tree in the left hand panel of the tool. Editing the app-folder-categories entry in the right hand panel is what adds the categories back for you. The default is [‘Utilities’, ‘Sundry’] and this needs to be changed to [‘Utilities’, ‘Games’, ‘Sundry’, ‘Office’, ‘Network’, ‘Internet’, ‘Graphics’, ‘Multimedia’, ‘System’, ‘Development’, ‘Accessories’, ‘System Settings’, ‘Other’].
Once the above has been completed, a change is noticeable in that you get a list of categories in the application overview screen and a split of application icons in the middle and categories down the right hand side. Clicking on a category brings up a new panel that contains the application within it and this can be closed again. Cycling through the categories is a process of opening and closing the different panels. The behaviour may be changed but the functionality remains and I have heard that this will be polished further in release 3.10 of GNOME Shell.
For those wanting to to exit all of this and get something like the old GNOME 2, it is possible to add the Classic Session. In Fedora 19, it’s a matter of issuing something like the following command:
sudo yum -y install gnome-classic-session
In reality, this is a case of adding a number of extensions and changing the panel colour from black to grey but it works without needing the category tweak that I described above. The Application Menu extension does need more stability hardening before I’d trust it completely though. There’s no point having a nicer interface if it’s going to freeze up on you too often.
