Hey,
The feature you are talking about is note title. Read more about it here at
https://www.zettelnotes.com/repository/. 'Content' is the note title that is parsed and set according to the behavior set in Zettel Notes repository settings. You can also set the title to be set from filename of the note.
With respect to the first feature, can you please share a video file or screenshots, that would help in solving this issue.
Regards,
Rohit
