I've tried installing it on the comicBook template myself and it seems to work OK.
I looked back at the code that the user posted and it seems they left out the switch for my code in their overall_header.tpl file, and they didn't copy it exactly as it is in the Mod installation file. Even though I've not been able to replicate the error as that user described it (refreshing when clicking anywhere on the page), I believe the reason it wasn't working was probably because they did not copy the code exactly from the installation file.
It should be safe to use it on the comicBook template, however if you're still having problems, double-check that you are using phpBB 2.0.22 and comicBook 1.0.3 because that's what I used to test the Mod on, and it worked fine.
Regarding the add-on - it will not be an add-on anymore because I have decided to include it in the Mod as a default feature. I will, however, keep a version of the Mod available (in a contrib folder in the next release) that does not include this feature for anyone who doesn't like it.
Depending on how much I get done today, it should be in the Mod Validation queue within the next couple of days.
The next version will be version 1.1.0 because of the new feature addition.
