Issues left:

• Preview in dark theme when no search results is still "white"
  
• Location of the pin to top button
  
• When clicking an entry in the search window, it should be marked in the corresponding library (JabRef should focus the library and then select the item in the main table)
• Search dialog has to retain size (-> store size in preferences)
• Debatable: If the columns such as status or relevant should NOT be shown, because one could theoretically change the value of them in the search window...
