The GS extensions that offer a classic applications or locations menu instead of or next to the Activities area are really more than enough. The GnoMenu is not just another addition in this category, but a menu extension that offers more than the usual…
GnoMenu offers all applications in categories, favorite apps on the left, search ability, list/grid view, logout, lock screen, advanced and system setting on the top left and restart shell, suspend and shutdown on the bottom left. Need a menu? GnoMenu is one of the most comprehensive things out there.
Enabling this extension not only add a menu, but also transforms the top left by replacing the Activities button with a View and an Apps button. View works like Activities while Apps is a shortcut to the Show Applications button.
Minimized Windows List
What this extension is good for is pretty obvious from its name. It simply adds a menu that lists all minimized windows from all workspaces with the windows on the active workspace listed first. Clicking on a menu item restores the window and jumps to the workspace it is on.
A good thing about this extension is that the list icon is not shown at all, until a window is minimized. This extension is very simple to use and will certainly make you utilize the minimizing concept more under Gnome Shell.
