Multiverse Feedback: Virtual Booster

Purple rarity    M  Suggestion I'd like to be able to make cards with purple expansion symbols.	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.	Recent comments area doesn't refresh    C    At the bottom of a card set's front page, the recent comments area doesn't refresh to show more recent comments. This is probably another cacheing issue.
Warn if about to lose unposted comment    C  Enhancement If you've typed a bunch of text in a comment box, but then click "Edit card" or some other link, the comment isn't posted. I could make Multiverse warn you about the unposted comment, like Stack Exchange sites do.	Multiple cardset admins    C  Feature There's currently no way to allow a few people to edit a cardset unless you allow all signed-in users to do so. There should be.	Split cards on cardset front page    C  Bug On a cardset front page, split cards can turn up twice in the "recently modified cards" list. There are also scattered occasions when clicking the highlight / unhighlight / etc buttons on that page don't work for comments on split cards.	CSV Export/Import of split/flip cards    C  Bug This just doesn't work at all. I should figure out a way to make it work.	New site name    C    Multiverse may be moving to its own domain, and multiverse.[com|net|org] are taken. It might be a good time to change the site's name, but to what?
Level-Up Cards    C  Feature Let us have a nice frame for creatures with level up.	Card art on tokens looks horrible    C  Bug	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.	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.	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?
