Neon https://extensions.gnome.org/extension/1401/bluetooth-quick-connect/ https://extensions.gnome.org/extension/2917/bring-out-submenu-of-power-offlogout-button/ https://extensions.gnome.org/extension/2/move-clock/ https://extensions.gnome.org/extension/4703/dock-from-dash/ or https://extensions.gnome.org/extension/307/dash-to-dock/ The last 2 depends on how the computer is being using I use dock from dash for my htpc and dash to dock on normal pc and set it up like the unity dock.
Neon Screenshot below is with both dash to dock (left of screen) and dock from dash installed, dock from dash uses autohide, which works well and should be part of the default install.
