Description samik 2017-12-19 19:08:47 UTC
While editing document local hyperlinks, the "Target in document" window appears if browse button is pressed for target. This shows a list of headings, among other things. This list of headings is flat in the sense that all levels of headings are shown in a single list like manner, with the heading's outline numbers prefixed. This should be changed into a hierarchical tree like widget, such as in navigator, so that it can be navigated properly when there are many levels of headings in the document. 
Additionally, also available in navigator, there should be a way to change verbosity level of heading list. Such as upto which level the headings are shown.

Steps to Reproduce:
1. Create a document with many levels of headings
2. Right click on a hyperlink, select "Edit hyperlink..."
3. In the edit dialog, go to "Document" tab
4. Press the browse button beside "Target in Document" > "Target" textbox
5. A "Target in document" dialog opens with a flat list of headings in the document"

Actual Results:  
A flat list of headings is shown in "Target in document" dialog. There is no option to control the level of displayed headings.

Expected Results:
A hierarchical heading tree should be shown like navigator. There should be a way to control the level of headings displayed in that dialog

Reproducible: Always

User Profile Reset: No

Additional Info:
This is problematic for documents with many levels of headings, especially a particular level is more crowded that others, because then other levels are lost in the list; it's very hard to cherry-pick them from within.
This happened to me while numbering source code listing lines with the help of chapter numbering(so that it automatically restarts on each listing), but then it creates a heading out of each source code line and other levels are lost in them.

This requires significant changes in the code to determine the level of the heading.
