It's fine. In the mean time, I'll just hold off on importing my comics and series until I can. If I imported them now, the individual files would just get in the way, since "random" is the primary way I browse.

I agree, but if that were to be done, then instead of it being hard-coded, there should be an option to set which tags get thumbnail priority, and maybe just have the tags you listed be the defaults. This ensures flexibility in the case that there are other groups of files where one kind makes obvious sense as the thumbnail.
