[itsme]

There's a tab called "Recent" (German: "Verlauf") showing the last songs that have been opened in MobileSheets. You can select the songs that should be part of your list (there are often some songs that were opened erroneously and were not played), call "Create Setlist from Songs" (Setliste aus Songs erzeugen) and use "Generate Songlist" (Songliste erzeugen) for this newly created setlist. 
You can specify which fields are shown in the songlist with Library Settings - Generate Song List Format (Bibliothekseinstellungen - Song-Listen-Format)
