Dynamic manga volume covers (ie covers change at the rate of TL, so that there are no spoilers)

[a1ntuw33bl3t]

So basically, some mangas have spoilers in their covers, so it would be cool to have an option of manga covers being tied to the TL progression. If the TL you're reading is at the 3 volume, you'll get the third volume's cover, and not the 20th, which might contain spoilers.
Another variant would be tied to your reading, ie the cover is tied to the last volume/chapter you read, so that it only depends on you

That's a planned feature, but it will be limited to only first or last cover, no ETA (search the forums there are replies about this from I think Bravedude)
