# How to display all the subsections' titles in navigation bar in beamer? [closed]

I want to modify miniframes theme in order to not display the bullets, but to show in the lower bar the titles of all the subsections of the current section. I did it modifying miniframe theme file: I eliminated \insertnavigation in the colorbox corresponding to sections and I inserted \insertsubsectionnavigationhorizontal in the colorbox corresponding to subsections as follows:

\begin{beamercolorbox}[center, ht=2.5ex,dp=1.125ex, leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
