[Feature] Toc's for subheadings

[tagd]

For long pages where some subheadings may contain a lot of data, it would be helpful to be able to create a TOC for a single heading.
Syntactically, I'd envision this like:
``` toc
toc_heading: "## my subheading"
```

In my case, I have pages for various pieces of software and a heading for courses with each course under it.
It would be useful to be able to navigate this note sections with their own TOC.

Example page

# Java
## Install
...
## Frequent functions
..
## Courses 
``` toc
toc_heading: "## Courses"
\```
### Course 1
#### Module 1
...
##### Section 1
...
### Course 2
...

Conversely, it might also be helpful to have an ignore heading function, where a heading and subheading may be left out of the TOC.

Thanks

Hey @tagd , I refined the feature request based on your original post. Can you tell me if I understand this correctly?

Thanks!

Example 1: Generate a TOC for a specific section only

Goal:
You want a TOC for just one section, not the whole document — for example, only under ## Courses.

Example markdown
# Java

## Install
Some installation steps...

## Frequent functions
Common function references...

## Courses
```toc
toc_heading: "## Courses"

Course 1
Module 1
Section 1
Section 2
Module 2
Section 1
Course 2
Module 1
Section 1

### 🔍 Expected plugin behavior

When the plugin sees:

```toc
toc_heading: "## Courses"

…it searches for the heading ## Courses, then scans only the content under that heading until the next top-level section (or end of file).

The generated TOC would look like:

**Table of Contents (Courses)**

- [Course 1](#course-1)
  - [Module 1](#module-1)
    - [Section 1](#section-1)
    - [Section 2](#section-2)
  - [Module 2](#module-2)
    - [Section 1](#section-1-1)
- [Course 2](#course-2)
  - [Module 1](#module-1-1)
    - [Section 1](#section-1-2)

This lets you have localized TOCs within long documents.
