Multiverse Feedback: Virtual Booster

Proxy    M    It would be a nice feature to be able to print proxy cards to play test with	Different card frames    U  Enhancement Stuff like the old frame, PCH planeshifted, and FUT futureshifted.	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.	Return to dropdowns after saying Custom    C  Enhancement If you select "Custom" in the Supertype or Watermark drop-down lists, that converts the drop-down to a free text entry field; but there's no way to return to the drop-down (apart from refreshing or clicking save-then-edit).
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.	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.	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.	Copy mechanics between cardsets    C  Feature It'd be nice if multiple cardsets could share a mechanic. Particularly obvious for several sets in the same block.	Expanding flip cards    C    I've noticed that when viewing flip cards with a good deal of text, if I try to expand the text, the font size increases but the text box doesn't increase properly. In addition, other fields don't seem to consider it necessary to move, so they cover up the words.
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.	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.	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	Troll    C  Creature – Troll We have a troll. Everyone should probably make their cardsets editable only by users.	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?
