Correct me if I’m wrong, but what you are asking for is not the existing Obsidian outline core plugin, correct?
If I understand correctly, you are asking for some way to automatically generate a table of content, for example at the beginning of the note :
- With hierarchy of sections (H1, H2, … represented by different levels)
- Each link redirects to the corresponding section header
- (What you are currently missing) Customizable styling for individual title levels (customize style for H1s, H2s, H3s and so on independently of one another).
As @Naranya suggests, have you tried using custom CSS with the best plugin you mentioned? You might be able to manually set the style you want this way.
Also a question, when you say the best is the last one, you mean dynamic table of contents? Isn’t this plugin unmaintained?
