Xubuntu at least has the whisker menu system, which gives you search bar in menu. Without it one can remove system menu and replace it with Xfce app-finder launcher. Then it's best to change a setting to place windows near the mouse pointer. Note: I'm currently not using Xfce at home, but I use some older version at work.
