Steps to Reproduce:
1. have writer document 
2. change / add / remove headline or TOC relevant element

Actual Results:
TOC not updated. Currently LO required the user to manually update the TOC via right-click on TOC > Update Index

Expected Results:
It would be more intuitive and convenient to automatically have LO update the TOC.


Reproducible: Always


User Profile Reset: No



Additional Info:
Obviously this raises performance needs. Maybe the documents I tested with were too small to cause any noticeable performance implications when updating TOC.

Also some logic would be required to not have LO update the TOC for every single keyboard press that is done. So whenever a TOC relevant element is changed, that could trigger a 30 second delay to update the TOC.

If this is a performance concern at all, a setting option could be added to disable / enable. But adding more settings isn't great.
