Hi, Habraludy!

After updating my distribution (Russian Fedora), I ran into a lot of problems in GNOME 3. In this article I will try to describe all the methods I have put together to solve them. Who cares, under the cat!

Quick Launch
For this you can use two options. The first is Avant Window Navigator. In this case, everything is simple. You will receive panels of this type:

The appearance of the panel is easily changed.
The second way:
intgat.tigress.co.uk/rmy/extensions/index.htmlDownload the archive for this link:
Expansion . We unpack in the home folder. Restart the user and ... the quick launch panel appears :) You will get something like what was in GNOME 2:

Now access to applications faster. See the screenshot:

Placing files on the desktop
For this you can use the Tweek Tool. My utility was not installed initially, but it can be installed via yum. Next, open: Tweek Tool -> File Manager -> Put a check mark (it is there alone).
And on the screenshot - Tweak Tool:

After that, all the files that you had on your desktop finally appear there. In addition, the context menu call from the desktop also works.
Various extensions
You can find all of them here:
gnome-shell-extension . With the installation on the site is very clear.
For example, System Monitor Extension is put by several commands:
mkdir ~/git_projects
cd ~/git_projects
git clone git://github.com/paradoxxxzero/gnome-shell-system-monitor-applet.git
mkdir -p ~/.local/share/gnome-shell/extensions
cd ~/.local/share/gnome-shell/extensions
ln -s ~/git_projects/gnome-shell-system-monitor-applet/system-monitor@paradoxxx.zero.gmail.com
sudo cp ~/git_projects/gnome-shell-system-monitor-applet/org.gnome.shell.extensions.system-monitor.gschema.xml /usr/share/glib-2.0/schemas
cd /usr/share/glib-2.0/schemas
sudo glib-compile-schemas .
Only one note: I didn’t have a Gnome Shell Weather Extension. After installing it, the Gnome shell stopped running. In general, the problem with him has not yet decided. Everything else works fine!
PS After all the manipulations, I got this desktop:

All the problems of GNOME 3 are solved and there is no desire to switch back :) Other interesting methods write in the comments!
Good luck!
PS Several users in the comments added other methods. For example,

Return buttons minimize, maximize .
