A while back I wrote about TopMenu, a panel plugin that provides global menu (AppMenu) support for MATE, then also included support for Xfce and LXDE.

Here's where Vala Panel AppMenu comes in.

Vala Panel AppMenu is a global menu panel applet for Xfce, MATE and Vala panels, which uses unity-gtk-module as its backend, and it works with all the applications supported by Unity's AppMenu.

MATE Dock Applet is a MATE Panel applet that displays running application windows as icons, which features option to pin applications to the dock, supports multiple workspaces, allows changing the MATE panel icon to the dominant desktop wallpaper color, and more.

The applets are highly configurable, allowing you to select the orientation, change the graph size, update interval, and it also ships with quite a few color schemes.

With the latest 1.4.0 release, Multiload-ng includes a Unity (and others) AppIndicator, as well as a systray applet. 

MATE Dock Applet is a MATE Panel applet that displays running application windows as icons. The applet features options to pin applications to the dock, supports multiple workspaces, and can be added to any MATE Panel, regardless of size and orientation.

The latest MATE Dock Applet 0.74, released today, includes a feature requested by some of you: it can now display Unity-like progress bars and badges on top of the icons, for applications that support this. You can see this in action, in the screenshot above, for Transmission.
