Instead of pinning multiple notes to the overview screen, which on some accounts was clogging up this page so much that the most important details such as balances were being pushed down the screen out of view, you can now define a memo for the most important information, and from the remaining notes you can mark the most important ones with a star.
If there is just a single starred note, the note summary will be shown on the overview.
However, if you have multiple starred notes then the number of such starred notes is shown and you can click through to see the starred notes only.
On the Notes tab, the notes filter enables you to quickly search by date, user, and text string. You can choose whether to view all notes or just starred ones.
