D2P is gnome shell’s dash + the top panel. D2P allows the top panel to be placed in 4 sides now.

Dash to Panel is an icon taskbar for Gnome Shell. This extension moves the dash into the gnome main panel so that the application launchers and system tray are combined into a single panel, similar to that found in KDE Plasma and Windows 7+. A separate dock is no longer needed for easy access to running and favorited applications.
