Multiverse Feedback: Virtual Booster

Proxy    M    It would be a nice feature to be able to print proxy cards to play test with	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.	Different card frames    U  Enhancement Stuff like the old frame, PCH planeshifted, and FUT futureshifted.	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.	Cockatrice integration    C  Feature Cockatrice is an open-source deckbuilder and gaming table. It supports set import from arbitrary URLs.
Multiple boosters    C    Actually, what I'd really like is to get the approximate numbers for contact sheets – one of each of the rares/mythics, random selection of foils and whatever rounds it out for common/uncommon. You can get it by hitting 'booster' a lot of times, but being able to get it in one go would be nice.	Rotating images doesn't work    C  Bug The "rotate" link on flip cards should see which of the Image and Mockup tabs is shown, and rotate whichever is showing.	Cropping roll-over image    C  Bug When the tooltip image is larger than usual, e.g. the default for a cardset is to prefer images to mock-ups, the roll-over displays the card image, but (at least for me) the right edge of the card gets cut off, removing the P/T, loyalty, and/or mana cost.	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.	Preview button for card editing    C  Feature It'd be nice if you could preview what a card would look like from the edit page. Particularly if you're trying to trim down the wordiness so that the text doesn't have to shrink so much.
Colour indicator    C  Enhancement DFCs, Kobolds, Transguild Courier and so on now have a colour indicator. We should be able to do that in Multiverse too.	Split/Flip card ease-of-use    C    The way it works now, with the frame selection opening a new selection box, seems to have an extra click or two. Instead, why isn't the box that says normal/split/flip always present? It will usually not matter, except when someone creates an alternate-frame card, when it become easier.	+ / - buttons don't work any more    C    Looks like an update to Chrome's DOM handling has broken them.	Return to previous page after login    C  Enhancement Not sure how feasible this is, but: if you're viewing a card, not signed in, and then you sign in, it'd be nice to return to the card you were viewing rather than be taken to the homepage.	Can't view large sets    B    If cardsets are too large, say for around 700 cards, I can't view them, instead Application Error shows up. This happens whether I use either visual spoiler or cardlist. Can you help me find a way to allow me to view a large cardset without experiencing problems or the Application Error?
