Dash to Panel, an icon taskbar for Gnome Shell, was updated to version 24, bringing support for vertical panel orientation (left or right of monitor), the ability to update the extension directly from the GitHub releases, and more.
The Gnome Shell Dash to Panel extension combines the Dash with the top panel into a single dock. This way you have running applications (and favorite/pinned applications), the tray, the system menu, and date / time indicator on a single panel.
Don't confuse Dash to Panel with the somewhat similar Dash to Dock extension (from which the Ubuntu Dock was forked from).
The extension comes with many features, including live window previews, panel intellihide, multi-monitor support, customizable appearance (including custom styles for the running application indicator), and more. There are also various minor, but useful features like launching applications pinned to the panel using the keyboard, add a Show Desktop button to the panel, isolate running apps by workspace or monitors, or dynamic panel transparency. It supports GNOME Shell 3.18 and newer.
