- Link aendern: nicht angebotene Berechtigung bleibt unberuehrt (Aktuell: ...), Zugriff nur bei ausdruecklicher Wahl gesendet
- Fehler je Abschnitt zugeordnet und geloescht; Aendern nur bei aenderbarer Freigabe; Kopiert-Anzeige laeuft ab
- Freigabe-Ansichten: stabiler Rueckruf, nur das juengste Laden gilt; Weitergaben mit Hinweis
- Ablaufgrenzen nach Serverdatum, Passwort-Erzeugung bis 256 Zeichen
- Dateiansicht blendet Neuer Ordner, Hochladen, Ablegen, Umbenennen, Verschieben und Loeschen nach den Buchstaben der Nextcloud aus
- Import-Reihenfolge nach biome check, Anleitungen und Changelog (10 statt 15 Freigaben, Suche ab einem oder zwei Zeichen)
