Any idea when 18.10 or 18.11 will be released? I am running on Manjaro and installed Sozi from the ArchRepository https://aur.archlinux.org/packages/?O=0&K=Sozi which means I am running Sozi 18.04-1523042682 and hence experience the automatic saving issue as well.
By the way, I am currently preparing my first ever Sozi presentation, and I am loving it. Will see if the audience does as well :-) 2 hours of content without any fancy layering etc.
Aside from the constant saving delays things work out well, what I haven't really understood is the aspect ratio subject because I am getting some strange results.
