I’m trying to have a linebreak in the title of a presentation with the Touying package, more precisely with the university-theme. The problem is that in the footer, the linebreak is unwanted, see screenshot below.
If you build your own touying template the solution would be fairly simple. You should insert in the definition of your footer #show linebreak: none.
In your case, I don’t find any easy solution. I have the same problem with the function mini-slides. To solve my issue, I had to modify the initial function. I may submit a PR to solve this issue.
