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.

The Screenlets package was removed from the official Ubuntu 16.04 (and newer) repositories because it no longer worked, however, Hrotkó Gábor fixed various issues that prevented the application and some of its widgets from working, and uploaded a new version to the official Screenlets PPA, for Ubuntu 16.04.

Using it, you get a new icon on the GNOME Shell Top Bar which displays the number of package updates, while from its menu you can see exactly which updates are pending, apply the updates, and more.

The extension provides numerous features, including the ability to move the panel to the top or bottom, change the panel size, live window previews, and more.

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.

Plotinus is a library that adds a searchable command palette to any GTK+ 3 application, similar to the Atom and Sublime Text Command Palette feature (or Unity HUD).

Update: the article initially mentioned Nemo 3.2. The PPA now provides Nemo 3.4 for Ubuntu 17.04 and 16.04 (Ubuntu 16.10 is no longer supported by Canonical, so Launchpad doesn't allow uploading new packages for it).

To make it easy to go back to Nemo 2.8.0 for Ubuntu 16.04 users in case something doesn't work properly (because there were quite a few under the hood changes in Nemo), I decided to upload the latest Nemo 3.4 to a new PPA.
