Multiverse Feedback: Virtual Booster

Card backgrounds on opera    C    Probably not a high priority, but using opera (11.51), the background colour for lands and multi-colour cards is bright cyan.	Levelers    M  Legendary Feature	Frequent Heroku errors?    U    I've been seeing a few Heroku errors on the page lately. It usually doesn't last, just half an hour or so, but it's a little odd. Wanted to ask about it in case it's slipped under the radar so far.	M15 flips are broken    U  Bug M15 flip cards render improperly, with the rare stamp jammed in the middle of the unflipped rules text, and the flipped P/T box trying to jump off the line.	Can't edit cards in Safiria    U  Ongoing Bug When using Chromium on Ubuntu 12.04, I cannot edit cards that I have created — instead I get the "We're sorry, but something went wrong" page.
Card history    C    When someone edits a card, they have the ability to comment on their change. I think it would be nice if there was some way to view older editions of a card as well, like on Wikipedia. That way, you could know what I used to have as flavor text here. ;)	OpenID signup and login    C  Feature Web users have too many passwords. Don't make people create a new one: let them use their Google account or other OpenID provider.	Comments on skeleton page    C    If I'm using a skeleton, then it's basically the main landing page for that set for me. Except I have to jump back to the other view to see comments. It would be nice to see a snippet of the last comment on each card; the red/yellow/white comment will take care of letting me find new ones.	Transform cards    C    I am not able to create any transform cards. Please Help	Skeletons not working    C    I make a skeleton and it produces the card codes table. But when I edit it or assign card codes it looks exactly the same. Not sure what's going on. I even waited until morning to see if it was a timing issue and nothing works. Tried making a new set, too.
Print without header/footer    C    The "Cardlist | Visual spoiler | Export | Booster | Comments | Recent activity Upcoming releases New card | Import data | Unaddressed" box still appears on printable links. Which pushes cards onto more pages than needed.	Error page mouseover and centering    C  Bug – Graphical If you hover over a link to a card that doesn't exist, the mouseover "image" loads from an error page, but since it uses a centered text box, it has the undesirable side effect that all the text fields on the existing page also become centered.	Can't generate a skeleton    C    I get error 500.	Same card codes    C    An option for cards fighting for the same slot. Not sure how the skeleton would/should display it, though. Same card code may go against how you already coded things, but an alternative could be something like "CL05b", idk.	More features for advanced search    B    Can you please give more features for searching cards on the advanced search page? I'd like features that allow us to search by mana cost and colors of the cards. These features haven't been added yet, but it would definitely help a lot if we can search according to mana cost, converted mana cost and colors because I'd like to see all the WUBRG cards in this website, for example.
