Customize multiple hierarchy symbols

Hello, I very much hope that obsidian can add the following functions and modify bugs:

  1. Can let us customize multiple level symbols, or after detecting indentation, we can also keep indentation in the reading perspective, because when exporting pdf, it often fails to indent because the list is not used (because I want to change the level symbol).
  2. All text under the title will be recognized as a code, and I hope it can be improved.
    I hope it can be accepted. Thank you

I cannot reproduce your second issue. For me, all text under the title is recognized as regular text.
