Make backlinks use multiple headings to distinguish between sections with the same name

[claremacrae]

Background

In #1150 it was logged that if the same heading name is used twice in a file, backlinks for tasks in the second section jump to tasks in the first section.

This is because Tasks back-links use only the immediate heading name preceding the task.

Obsidian linking to headings

I learned recently that multiple headings can be used in links.

For example, consider this note:

# delete me

A file with two headings called X

## H1

asdfafda

### X

afaf

## H2

asdfasdfsa

### X

asdfasdfadfa

Here are some possible ways to link to the X sections:

## Links

[[delete me#X]] always jumps to first X section
[[delete me#H1#X]] correctly jumps to  first X section
[[delete me#H2#X]] correctly jumps to  section X section

The Idea

Change tasks so that it tracks all the parent headings for each task (well, each section) - and then either include all headings in each backlink, or alternatively, detect if there are duplicate heading names in a file, and then include the extra headings.

It won't solve all cases, but it will help with some.

This is about the URL that backlinks jump to, to make sure that they navigate to the correct section more frequently.

See the related #1305 for changing the displayed text in backlinks in cases to help in cases where there are duplicate heading names in the file.

Thanks @claremacrae for this idea.
Related to the use case you describe, here is why I think it would be great to let user choose to to display full title hierarchy :

# Subject 1

## 2022-11-03
- Some text
- [ ] one task of subject 1

## 2022-11-08
- Some other text
- [ ] another task of subject 1

# Subject 2

## 2022-11-03
- Some text
- [ ] one task of subject 2

## 2022-11-08
- Some other text
- [ ] another task of subject 2

Is rendered :

It would be more useful for me to see something like (I really need this) :

Hi, thanks for the suggestion. once the title of this task is completed, this topic will be closed.

For this reason, it really helps to have only one subject per post.

Feel free to log your suggestion on a separate feature request, with the full text again, and linking to this one for context. Many thanks.

(In case it is not clear, this one is purely about the link in the back link, not the display text.

Finally, I hope I read your request correctly as am on a small phone screen!)
