Would really appreciate the how to add comics at some point. Other than that:

Viivi & Wagner found here http://www.hs.fi/viivijawagner/ if it's as simple as changing the URL(which I doubt :P)

And something that I still would find really useful is a button that lets you jump to first comic. Like lets say I want to read Sinfest from the beginning, and it's now in comic 3000 or something. Bit too much work to hit the back button 3000 times :P
Even more awesome would be to be able to type the number of the comic so it would jump to that, but as different comics use different numbering, I'm guessing that's impossible?

Also not sure if possible, but in the comics list could you have the sorting so that the ones picked would be at the top of the list? Or well that's just my preference, what do you others think?

I'm also guessing it's impossible to make the browser mode open faster when clicking on a comic? Now it takes couple of seconds to open. Again a fullscreen app might be nicer than using a browser, as you could add functions to read next strip and so on. But don't wanna push my luck :P

All in all. Great work mece! Thank you!
