Overview reduced to window/workspace selector only (if auto hiding of workspace selector becomes annoying please set dynamic workspaces to OFF in Tweak Tools and same time set minimum of 3 static workspaces, in my opinion this provides far superior experience) If not using tools like synapse and still in need to search for applications in Overview than this is doable - please start typing in application name you would like to find - using ESC, backspace may help learning how this works initially since you wont see what has been typed in thanks and hope people find extension useful
