I experienced the fact that the `title` put in YAML options is not rendered in `ipynb` output format. 
I think that parsing the title, when it exists, into a level one header at the beginning of the file might be useful.

I came across the following python code to tweak the `qmd` file, it can be used as an inspiration if you are okay to implement this featuere (I know that you will not use python for such implementation but if it can help you I am happy to share):

```python
import re

filename = "example.qmd"

with open(filename, 'r', encoding='utf-8') as f:
    text = f.readlines()
    new_text = "".join([line for line in text])

yaml, text = s.split('---\n', 2)[1:]
title_search = re.search('title: "(.*)"', s)
if title_search:
    title = "#" + title_search.group(1)
else:
    title = ""
new_md = title.replace('"', '').replace("'", "") + \
             "\n" + text
```

(Maybe there are other `quarto` YAML felds that could be parsed: I proposed title as a starting point)
