Multiverse Feedback: Virtual Booster

Purple rarity    M  Suggestion I'd like to be able to make cards with purple expansion symbols.	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.	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.	Allow Custom Symbols    C  Feature Allow us to specify small symbols/icons to be included on cards. If we were creating our own mana symbols like snow or Phyrexian mana , at the moment we couldn't have those images display on cards at all.
Card transfer    C  System update – Suggestion Put a copy of target card from a set you own into another target set you own. This would allow set designers to store cards that aren't quite ready for set inclusion, or to "slide" cards from one set they're designing to another. Illus. SFletcher	Tooltips don't appear if hovered too quickly    C  Bug If you mouseover a Gatherer tooltip (a [[[link to a printed card]]]) before the page has loaded, then the tooltip won't show, and won't even show if you re-mouseover the same link after the page loads.	Sabotage!    C  – Concern I don't know if cmeister2 is messing around with his own account, or if someone else is sabotaging his work, but his 5 normal cards have become experimental garbly-gook. This could bode unwell for the editable format.	View cards before publish    C    It would be nice if there was a button that allowed us to see what the finished card would look like before we create them.	"Hide flavour text" button    C  Enhancement SFletcher suggests a switch to make flavor text visible/invisible. This would allow us to look at a card's rules text alone for reviewing clutter.
My Cards    C  Enhancement It'd be nice to have a global link to My Cards (i.e. ones the current user has created), or My Recent Cards, or something.	Tagging users    C    In a comment, there should be a way of tagging users, e.g. (((dude1818))) becomes [dude1818](http://multiverse.heroku.com/users/57/). This would require the ability for notifications first, but this is an added feature.	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.	Innistrad Skeleton    C    In the Generate Skeleton Examples, It would be nice to have Innistrad appear as one of the examples. It's one of the few modern stand-alone sets that doesn't have something funky going on with the numbers.	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?
