Thanks for a quick reply and congrats on the great release! I understand that this is not a valid YAML. I am also not trying to paste the text directly in the Properties section. Let me give more context: most of my notes are using inline properties simply because it was not previously possible to create links to other documents inside YAML. With the latest release I want to convert back to YAML since now it is possible.
My expectation was that Properties panel, while giving access to custom UI, will also keep the option of editing content as plain text, and without causing it to lose data. This way I would be able to adjust formatting to fit correct YAML.
