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.	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.	Different card frames    U  Enhancement Stuff like the old frame, PCH planeshifted, and FUT futureshifted.	Get emailed when things happen    C  Feature Let people subscribe to a card, or a cardset, and get emailed when comments are posted and/or edits are made.
Transform cards    C    I am not able to create any transform cards. Please Help	Cards remaining is skeleton after removal    C    I moved two cards from my set Convergence to Infinite Potential Well. For some reason, they're still showing up on the skeleton of Convergence.	Support "active" status better    C  Enhancement Currently, the Visual Spoiler includes non-active cards, and the cardlist includes them by default too. I should let cardset owners specify how non-active cards are treated.	Printable?    C  Bug Whenever I click on the the "Printable" button in the Visual Spoiler, I get an error message, in both Chrome and IE.	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.
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.	Lower case symbols    C    Can we pretty please support ?	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.	Unshrink small card text    C  Feature On cards with too much text, it can be hard to read their rules text. Add a button on the card's page to expand the text up to readable size (and stretch the card frame out of proportion).	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?
