Hi,
I will add this as a feature request, to have randomly selected results in the auto populated list. Unfortunately there is no workaround of it now, but should be available in the next release.
Also, there is an option on the Layout Options -> Results behavior panel, where you can turn off the results closing on document click: http://i.imgur.com/QXvAUv9.png
That should do the trick 🙂
