"Execute" is a rather geeky term, I would say that "Launch" is more understandable and welcoming for a normal user.
Created attachment 2441 Patch implementing this This patch changes the label of the button to "Launch" and changes the checkbox to "Close after launch".
This is fixed in revision 30225: * src/xfce-appfinder-window.c: Don't use startup notification for now. As we use exo-open to launch desktop entries, people usually end up with annoying waiting cursors and a lot of temporary exo-open items in the taskbar. Add tooltips showing the categories and command for each item in the tree view (original patch by Jérôme Guelfucci). Use "launch" instead of "execute" in the GUI (patch by Jérôme Guelfucci, fixes bug #4968). Add support for searching the Exec field of desktop entries (original patch by Jérôme Guelfucci, fixes bug #4969).
The button is still labelled "Execute". I'll attach a patch to fix this.
