Minha barra de navegação no Beamer é muito longa devido à forma como está formatada atualmente. Considerei usar várias linhas para a navegação circular, mas isso faz com que o espaço vertical da barra de navegação ocupe muito espaço. Parece que me lembro de ter visto em algum momento uma apresentação em que os círculos se reduziam a um único círculo, a menos que realmente estivessem dentro da subseção atual, onde eles se expandiam novamente para ter pontos para cada quadro naquele ponto.
Eu apreciaria sugestões sobre como manter a barra de navegação de linha única como a que tenho, mas maneiras de condensar a barra para que caiba na largura que tenho.
Também me lembro de ter visto uma apresentação em que havia linhas entre os marcadores de navegação circular para cada subsubseção da apresentação, mas ainda não consegui encontrar algo sobre como fazer isso. Se você pudesse me indicar onde isso pode estar localizado, seria ótimo.
Desde já, obrigado.

Os miniquadros do modelo beamer possuem 3 modelos predefinidos:
[default]mostra pequenos círculos como miniquadros[box]mostra pequenos retângulos como miniquadros[tick]mostra pequenas barras verticais como miniquadros
Então você poderia, por exemplo, simplesmente mudar para o tickmodelo, pois ele não ocupa tanto espaço:
\setbeamertemplate{mini frame}[tick]
\setbeamertemplate{mini frame in current subsection}{tick}
Mas parece que você deseja manter os círculos. Então, por que não apenas reduzi-los? Para fazer isso você precisa redefinir os mini framemodelos. Então, apenas copiei o defaultmodelo, renomeei-o scaled circlee introduzi um fator de escala.
\defbeamertemplate{mini frame}{scaled circle}[1]
{%
\begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
\pgfsetlinewidth{#1 * 0.4pt}
\pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
\pgfusepath{fill,stroke}
\end{pgfpicture}%
}
[action]
{
\newlength{\myminiframesize}
\setlength{\myminiframesize}{0.14cm}
\newlength{\myminiframeoffset}
\setlength{\myminiframeoffset}{0.03cm}
\setbeamersize{mini frame size=#1\myminiframesize,mini frame offset=#1\myminiframeoffset}
}
\defbeamertemplate{mini frame in current section}{scaled circle}[1]
{%
\begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
\pgfsetlinewidth{#1 * 0.4pt}
\pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
\pgfusepath{stroke}
\end{pgfpicture}%
}
\defbeamertemplate{mini frame in current subsection}{scaled circle}[1]
{%
\begin{pgfpicture}{0pt}{0pt}{#1 * 0.1cm}{#1 * 0.1cm}
\pgfsetlinewidth{#1 * 0.4pt}
\pgfpathcircle{\pgfpoint{#1 * 0.05cm}{#1 * 0.05cm}}{#1 * 0.05cm}
\pgfusepath{stroke}
\end{pgfpicture}%
}
Você pode então simplesmente carregá-lo com
\setbeamertemplate{mini frame}[scaled circle]{0.7}
\setbeamertemplate{mini frame in current section}[scaled circle]{0.7}
\setbeamertemplate{mini frame in current subsection}[scaled circle]{0.7}
onde 0.7está o fator de escala.
