### 2/5 — Unausgereift

*2021-09-26*

Da ist noch sehr viel Luft nach oben! Abgesehen von den regelmäßigen Abstürzen und Verbindungsverlusten ist die Übertragung aller Daten, die bei jeder Verbindung aufs Neue stattfindet, megalangsam. Die Möglichkeiten sind sehr begrenzt.
Ach ja: das Unterschriftsfeld ist auch eher unbrauchbar…
