Proton's document features are extremely limited. It feels more like Wordpad or Notepad. Here is a list of the things that are missing, and preventing me from migrating from Google to Proton docs.

Critical:
- No actual pages! Thus, no page setup, page orientation, pagination, page breaks, header & footer.
It's just one long page and it doesn't show the document as a white sheet on a gray background. It's all white.
- No document chapter outline,
- No columns, no text highlighting, no text wrap around images, extremely limited (and annoying) tabel options.

Nice to have:
- line-heights,
- grammar check,
- better image options,
- much better table options
