Eigene Footnoote Befehle

Für das Erstellen einer Seminararbeit soll ich eine LateX Vorlage, die mir etwas veraltet erscheint, vewenden. Ich habe über Overleaf ein Projekt erstellt und die meisten veralteten Paketnamen wurden mir gleich rot angemalt und eine Korrektur empfohlen. Die aktuelle Fassung ist als VORLAGE abgebildet.

Zu meiner Person, muss ich leider noch mit rudimentären Kenntnisse von LateX begnügen. Anspruchsvollere Anpassungen habe ich daher aktuell nicht selbst hinbekommen.

Ich würde mich freuen, wenn mir jemand auf evtl. veraltete Pakete der usepackage Welt hinweisen würde, oder eine Beispiel aufzeigen könnte, wie ich meine Hauptdatei verändern muss, um folgende zwei Probleme zu lösen (Problemlösungen zu integrieren):

1. Gliederung nach juristischem Format (Habe Mit Hilfe von Stackoverflow in einem separaten Projekt etwas zaubern können. Siehe nach nach der Vorlage (Hauptdatei)
2. Fußnoten sollen je nach Quelle unterschiedlicher Formatierung auf jeder Seite angezeigt werden Lösung gefunden, nur kann ich die nicht bei mir einbauen, verwenden. Nur als separates, neues Projekt.
