# How to keep highlighted the mini frames of already discussed slides?

I would like for the dots in the mini frame of my beamer presentation to be full circles and remain highlighted once I already discussed the corresponding slide. Let me make this clearer: when you are showing a slide of your presentation, the corresponding dot in the mini frame on top highlights in order to make the audience follow you up. I would like, once I change slide, for the already coloured dots to remain coloured in black. Like in a loading bar. Is that possible to achieve in a simple way? I have, unfortunatly, no time to create my own theme :) Thanks a lot in advance to anyone who will have the time and patient to answer.

\documentclass{beamer}

% Stile for Beamer
\usetheme{Singapore}
\usecolortheme{rose}
\usepackage[english]{babel}
\useoutertheme[]{miniframes}

\begin{document}

\section{hello}
\subsection{}
\begin{frame}
hello
\end{frame}

\begin{frame}
hello
\end{frame}

\end{document}

• Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – jub0bs Apr 9 '14 at 14:59
• Like the coloring schema I suggested in my answer to tex.stackexchange.com/a/111473/3954? – Gonzalo Medina Apr 9 '14 at 15:02
• I have added as requested a sample of my code. – yrret Apr 9 '14 at 15:12
• Yes like you did in [tex.stackexchange.com/a/111473/3954] but the other way around. You made it disappear, I want them to appear. Thank you @GonzaloMedina – yrret Apr 9 '14 at 15:16
• @yrret Is the coloring schem of my answer below what you are trying to achieve? – Gonzalo Medina Apr 9 '14 at 15:25

This seems to be a variation of part of the code I provided in this answer to Beamer: how to change the mini frames from circles to rectangles. Here's is the required code (change the color specifications according to the color schema of your theme, if required):

\documentclass[compress]{beamer}
\usetheme{Singapore}
\usecolortheme{rose}
\usepackage[english]{babel}
\useoutertheme{miniframes}

\definecolor{dark-gray}{gray}{0.10} %color for the navigation squares

\makeatletter
