[missing cover] exists @akashako, [missing pages] does not. this is a rename

Missing cover is a missing page, yes. However missing pages is not nessesarily a missing cover. Pages from the middle of a gallery may be missing that are not covers. There are galleries that have missing pages that do not fall under missing cover. A new tag should be made to include all 'missing cover' galleries.

@akashako Elaborate? Missing cover is a missing page, is it not?

If this gets accepted it's just going to create a mess.

I hope this gets accepted eventually. They really need to repurpose some of the tags

An alternative that preserves the missing cover tag: create tag missing pages +7
