Regarding current desktop usability: Please capture scrolling and interpret it as swiping. I have to click twice to 'swipe' to the next one. I don't want to click unless I'm leaving the page or POSTing something.
Also, I suppose you might like to earn some money with this. I found an interesting typeface but wasn't even able to Google it at first, because the spelling was wrongfully auto-corrected. A button with an affiliate link to buy (or simply download if the typeface is free) is what would make this app really useful.
Thanks for sharing this, I'll be keeping an eye on you. Good luck!
