Hell, anyone working, reading, or coding the interface on a webcomic focussed on chapter-based stories oriented in portrait orientation is very likely to have valid input here.
I got hooked on Inverloch, but was severely disgusted with the interface for navigating the archives. In particular, the page ended up pixels too tall for me to click on the next button without scrolling the screen each time, so it made slogging through the archives very arduous. Not to mention, well, I'm running a widescreen laptop. One page at a time was annoying too, but the 'move-scroll-move-click' routine was getting old fast. (Yay for not having a wheel-mouse.)
So... I started writing my own interface. I just recently e-mailed the lady that writes and draws the comic, and maintains the website, but haven't heard back from her for better or ill for about half a week now when I told her about my work in case any of it was useful to her. At this point, I haven't heard back, and can verify through server-logs that she hasn't visited the 'demo page' I set up on my website either, so I'm guessing either it'll be a week or two before she gets back to me due to mail-volume, or my e-mail got caught in a spam-trap either automated or mental skimming over the e-mail and thinking it was an ad.
My alternate interface for Inverloch
Note I specifically only have the first nine pages viewable as I'm locally-cashing those pages (the first 'act' in chapter 1) on my web-server to prevent polluting the server-access logs and referrer-logs for Inverloch. Navigation works all the way up to the latest pages posted as of today, it just will load 'bad' images.
