Varning för fulkod, men något sådant här gör jobbet (vet ej om tillåtet).
Körs i Console i Browsern ifrån relevant tråd som du vill hämta ut. Varning igen: om tråden är lång finns risk för att scriptet fryser eller kraschar.
Koden öppnar en modal där alla poster inryms i ordning. Utskriftsfunktionen är inte funktionsduglig ännu.
