Close RecentX window after accessing an item from the list

Question

When I double-click an item in the result-list to open it (in its associated application), the RecentX window remains open. I would prefer to close it in this case. So please add an option to Preferences: Checkbox - Close the RecentX window when opening a result-list item. 

Is there any other way to do this currently in RecentX?

Answer 1

This is because the red pin (First button in the below picture) may be down. That is the 'Stay on Top' option. Just click on it again to auto hide the RecentX window.
