How to write text into a file in reading mode

Goal:
I wanna have a page (probably in reading mode), where I still can write markdown-text into.
I wanna have the file in reading mode, to secure elements of being changed and also have a better user-experience. I wanna have the ability to getting suggestions for links and tags.

Options:

  1. Metabind inline-text area.
  2. Metabind editor-input-field.
  3. Use two pages.
  4. Placing a page in my main file, via ![[Filename]].
  5. Lock some are of the page, so no changes can be made, and cursor can’t be placed there.
  6. Spit the page in a section in reading- and a section in writing-mode.

Problems with options:

  1. Is not showing suggestions
  2. Is not showing suggestions too, but rendering markdown text.
  3. Is not fulfilling the need of having both on one page.
  4. There I can’t interact with the dataview-tables of this file.
  5. Don’t know a way to do that.
  6. Don’t know a way to do that.

Does someone know a solution? Are there Obsidian internal text-input fields, for files in reading mode? Can I build my own one, with code or a specific PlugIn which is working with code?

Thanks for your help.
