Avoid title duplication
The first line of the note is considered its title. Fine. But please don't repeat the title below the note in card view. Most quick notes are just one liners. The current UI is overkilling (although I know there's a list view): a mostly empty square with a text at the top and exactly the same text below.
Here is an idea: if there are at least two lines and the first one is separated from the rest by an empty line, then consider the first one a title and show it in bold inside the card.
Here is another, simpler: keep the statu quo but otherwise omit the note footer, let the note speak by itself.
This intrigues me: the examples in the user manual have a footer that's not contained in the card text. That not seems to be possible to achieve in the current UI.
