I've been looking for a simple outliner for Mathematica notebooks and found Yuri E. Kandrashkin Sidebar'TOC, but decided I need something simpler and dynamic.

Has anyone tried making a dynamic outliner before?

This is what I've came up with so far:

Outline[] := 
      NotebookRead /@ 
        CellStyle -> {"Section", "Subsection", "Subsubsection", 
        style : "Section" | "Subsection" | "Subsubsection" | 
          "Subsubsubsection", ___, CellID -> id_, ___] :> 
          Ceiling[(StringLength[style]/ 3)] - 2] <> " " <> name , (
         NotebookFind[SelectedNotebook[], id, All, CellID];
         SelectionMove[SelectedNotebook[], All, CellGroup];
         ), Appearance -> "Frameless"]], UpdateInterval -> 1]], 
  WindowSize -> {Fit, 550}, WindowFloating -> True, Saveable -> False,
   WindowTitle -> (WindowTitle /. 

and here is how it looks in action (the section names are clickable): Outline

I invite everyone who sees this as a useful little thing, to play with it/make it prettier/more useful or just accept it as a small community contribution.

  • $\begingroup$ Hi! I'm happy to share it with you. Please note that it uses latex fonts, which are also written in the repository in .otf format $\endgroup$

  • $\begingroup$ Thanks, I will try it out on first chance I get. $\endgroup$ Jun 10, 2017 at 13:30
  • $\begingroup$ The repository has since moved to Science Notebooks $\endgroup$
