Many presentations include some kind of a visualizer where the listeners can easily see how far the presentation has gone.
A great option to do so is adding a `progress bar` into the slide layout.
----------
**Minimum Working Example (MWE):**
The user [Gonzalo Medina][2] has posted a nice approach on how to display a triangle above a line:
[![Screenshot of the code from user Gonzalo Medina][3]][3]
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{calc}
\definecolor{pbgray}{HTML}{575757}% background color for the progress bar
\makeatletter
\def\progressbar@progressbar{} % the progress bar
\newcount\progressbar@tmpcounta% auxiliary counter
\newcount\progressbar@tmpcountb% auxiliary counter
\newdimen\progressbar@pbht %progressbar height
\newdimen\progressbar@pbwd %progressbar width
\newdimen\progressbar@tmpdim % auxiliary dimension
\progressbar@pbwd=\linewidth
\progressbar@pbht=1pt
% the progress bar
\def\progressbar@progressbar{%
\progressbar@tmpcounta=\insertframenumber
\progressbar@tmpcountb=\inserttotalframenumber
\progressbar@tmpdim=\progressbar@pbwd
\multiply\progressbar@tmpdim by \progressbar@tmpcounta
\divide\progressbar@tmpdim by \progressbar@tmpcountb
\begin{tikzpicture}[very thin]
\draw[pbgray!30,line width=\progressbar@pbht]
(0pt, 0pt) -- ++ (\progressbar@pbwd,0pt);
\draw[draw=none] (\progressbar@pbwd,0pt) -- ++ (2pt,0pt);
\draw[fill=pbgray!30,draw=pbgray] %
( $ (\progressbar@tmpdim, \progressbar@pbht) + (0,1.5pt) $ ) -- ++(60:3pt) -- ++(180:3pt) ;
\node[draw=pbgray!30,text width=3.5em,align=center,inner sep=1pt,
text=pbgray!70,anchor=east] at (0,0) {\insertframenumber/\inserttotalframenumber};
\end{tikzpicture}%
}
\addtobeamertemplate{headline}{}
{%
\begin{beamercolorbox}[wd=\paperwidth,ht=5ex,center,dp=1ex]{white}%
\progressbar@progressbar%
\end{beamercolorbox}%
}

**Question:**
This looks nice indeed, but I would prefer to add the `section titles` into the timeline as well.
[![Screenshot of the desired progres bar][1]][1]
Hereby you can see:
- *Introduction* and *Motivation* has already been presented
- *Methodology* is currently presented
- *Results* and *Conclusion* will be presented afterwards
Would it be possible to extend the code so the section titles will appear in the timeline as well?

One can modify https://topanswers.xyz/tex?q=587#a640 a bit to add the section names and numbers:
```

\usepackage{tikz}
\usetikzlibrary{patterns.meta}
\setbeamertemplate{headline}{%

\begin{tikzpicture}
