Task bar in the top panel, tasks on all workspaces, focused window title. Basic actions, nothing more : activate, minimize, switch, desktop overview. Some easy settings in extension.js and css files. This extension hides (if setting is on) the unneeded Activities button and makes the Places Menu extension's label become a folder icon (needs to turn off and on Simple Task Bar). This extension is light and should not interfere with GNOME Shell behaviour+logic. If you want more, please consider installing Dash to Panel. Give a try to Horizontal Workspaces + Workspace Indicator (official extensions) to get a classical setup.
