Notes has no save option and does not reliably save

I'm using Notes in Linux Mint 21 Cinnamon. When I type some notes into a sticky note and click outside the note, I would expect it to get saved. But immediately after, when I use halt -p at the terminal to shutdown the computer, and after I start the computer again, I notice that some of the latest sentences I typed into that note are not there anymore. So either you need to ensure that the notes get saved as they are being typed, or you need to provide a save button and/or a Ctrl+s option to save the notes.

For now I'm so disappointed with Notes, that I'm just going to create a file with GEdit and use that file to store my notes. That's a lot more reliable.

ps: Another little reason I didn't like Notes, was because of the limited color options you have. I wanted to create some less-conspicuous grey coloured notes. Rather than provide a limited number of color options, you could provide a color wheel to allow users to choose any color they like. There are various tools which will automatically pick the right foreground color for any chosen background color.

No files, tests, or entry points are named. Reproduce the Notes workflow on Linux Mint by typing text, clicking outside the note, shutting down with halt -p, and checking persistence after restart; define whether the fix is reliable saving or an explicit save action, and treat the color-wheel request as separate scope.
