• datum gleiche einrückung wie das datum
• datum sollte überschrift sein und prominenter gestaltet
• datum braucht Wochentag
• mittlere spalte linksaligned
• Indikator ob Stundenthema richtig gespeichert wurde (@yuha )
  • when hovering over icon & success: show some fancy success message
  • when hovering over icon & error: show error message

• Remove outer card
• Move search, group select, ... into an app bar (see also this)
• Bottom sheet for date select should not be full width of screen (@yuha )
