This question is in reference to How to remove navigational circles and fit the navigation bar titles in Frankfurt beamer theme? (I would simply add a comment to diabonas' answer, but I don't have enough reputation - is there a way around this?)
Anyway, I wanted to achieve a similar result to the user who posted that question, and the solution provided works well, except I would prefer the most recently highlighted circle to remain highlighted whilst we set
\miniframesoff. How could I go modifying the code to achieve this?
