Multiverse Feedback: Virtual Booster

Proxy    M    It would be a nice feature to be able to print proxy cards to play test with	New OGW Mana    M  Creature – Eldrazi Devoid (This card has no color). Can someone add the new colorless mana symbol ?	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.	Different card frames    U  Enhancement Stuff like the old frame, PCH planeshifted, and FUT futureshifted.
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.	Move cards between cardsets    C  Feature It'd be nice if we could move cards between cardsets we own. At the moment you have to delete it from one and create it in the other, which loses the edit history and comments.	Leveler Creatures    C    Personally, I'd like to see something that would create the "leveler" creatures from Rise of the Eldrazi card format. Hope that makes sense. :D	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.	Images for set symbol/rarity    C  Feature I should allow people to specify images for their set symbol for each rarity, to be used instead of the current "bold letter in a box" if provided.
Position of tooltips in small window    C  Enhancement I'm not sure if this is just me, but when my browser window is the wrong size (say, just fractionally less than the height of a preview), the preview tends to bottom-align with the link, but aligning with the top to the top of the window would be more visible.	Application Errors    C  Error Frequently getting these Application Errors. On some days it's really bad. Loading a cardset or page requires many tries. If working on a new card, it could mislead you to resubmit several times, thus creating multiple copies of the same card. I assume this server runs on ASP.NET because I only ever see these errors on ASP served pages. Quite often, actually, not just this site.	Skeleton generation is broken    C  Bug "Generate skeleton" gives an error for all cardsets. I think line 295 of cardset needs fixing.	Can't generate a skeleton    C    I get error 500.	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?
