Suppress display of pages in a comic

Many comics posted are full of non-comic material like advertising, letters pages, 'brag images' by the scanner, etc. I'd like to be able to see a set of thumbnails of all pages of a comic , select a number of them, and mark them as not to be displayed when reading the comic.

The needed changes for all your suggestions are related, so I should have to do everything at once.

I am not sure when I am going to have time for doing it, so I can't give you an ETA.

Thanks!

Even without a fancy thumbnail based user interface having a blacklist in form of "negative bookmark list" per comic could be a useful feature. As it's non-intrusive, it shouldn't be too hard to implement.
Thanks for the suggestion.

I would love to see a feature like this. Even better would be a feature that would allow you to delete pages from the .cbr/.cbz file itself. I hate having to unzip/unrar files, delete the images I don't need to save space, and then recompress the files.

Simple Comic reader for OS X claims to have this feature, but I have never seen it actually work. I have tried it numerous times. Comic Rack for Windows also has this feature, and it apparently works as advertised.
