Well... correct me if I'm wrong, but your program is meant to create comic book files (CBZ/CB7/....) not edit them. If you'd like, I'll be happy to admit that I'm lazy. Yes, I could instead (manually):
A) rename comic book file to .ZIP or .RAR
B) extract all files into a folder
C) view all files with my primary single image viewer and delete as I go
D) re-compress all the files into a .ZIP or .RAR (I prefer ZIP)
E) rename the extension back to .CBZ or .CBR
The way I see it, your program would only allow me to combine steps D and E together. Not to mention that I still have to give it the same name it had from before.
I guess I'm trying to automate things as much as possible. Of course, the best option would be for my comics viewer (ComicRack) to allow me to do that, but the only thing it will do is to allow me to mark the desired images as hidden (it's called deleted in the program, but they are actually hidden.) And then if I send these files to someone else or one of my other devices, such as my tablet, the unwanted pictures are still there and reappear, thereby defeating the intent. Of course my last option above (the renaming of the extension) would leave the file there, but at least it would not be viewable at all.
Lastly, I'm sorry if I have misunderstood the capabilities of CBAR, because I have downloaded it and used it for making them, but as I said before, it seems like it can only create CB archives, and all the editing is still left to me like I mentioned above.
Thank you, though.
