Tested only with Firefox using stylish!

Will look different on each supported site. The screen shot is just an example.

The original version just shoved the entire page up. Now it is a bit more sophisticated, but I will keep the name.

Hopefully the style recognizes, if You are in a manga or somewhere else. So there is no real need to switch it off anymore.

On overview pages, it will expand the short description of the manga.

note:
This will not get any updates, because I made a https://greasyfork.org/en/scripts/12945-cats-webcomic-tool now. User scripts are way more flexible and powerful.
