I'd like to know how the vertical navigation in the
beamer sidebar can be edited to have the section numbers aligned left like in a toc.
The question is very similar to this one I think the MWE can be used, too.
To make clearer what I want to achieve I uploaded a picture of a beamer theme (non-public) having the alignment implemented:
As you can see the section number is fixed left of section title and the subsection starts at the exact same x-position like the section. Also line break start at that x-position. Also other texts like title are fixed at this position.
Thanks in advance!
