Outlines - rzukic/zed-latex GitHub Wiki
This extension provides outlines for parts/chapters/sections/etc in LaTeX files, and also entries in BibTeX files, labelled by their titles. This can be seen in the breadcrumbs below the tabs to determine the context of the current cursor position. This can also be use in the "outline panel" (accessible from a small icon at bottom of window or ctrl+shift+B).
