Once a chapter is loaded, could you start loading the next chapter in the background? Some examples would be like this:
http://manga.redhawkscans.com/ or like this
http://userscripts.org/scripts/show/59842. You could display how far preloaded the next page is by putting a progress bar on the "Next" Button (e.g. "Next (42%)", "Next (88%)", "****Next****")
**** where it's bolded once it's 100%, or maybe some other UI thing? idk... ****
Also, i was wondering if it's possible to use a double keytap as a keyboard shortcut? So like if you wanted to go down half a manga page you press the right key once, but if you tap it twice quickly in succession it'll jump to the top of the next page (?) not quite sure if this is possible, reasonable, or a good idea, but maybe could be interesting to test out? examples are on redhawkscans (^link above)
P.S. How's it going polo? We haven't heard much from you recently!
