OK. I've downloaded MComix 1.02 and, despite having a bit of trouble installing it, it is now on my machine. And it works. It seems quite simple but it does access everything in a section, ie. documents, and I prefer to have only 1 comic showing at a time. As it is, it seems to run right on the the next file in a folder automatically. Only a small thing I'm sure but now that I have CDisplay installed and feel comfortable with it, I will tend to stay with it and Comical - which is really simple and straightforward.
Anyway, I read most comics on an Android tablet, using PerfectViewer, which has arguably the best .pdf reader for comics and storypapers.
