Multiverse Feedback: Virtual Booster

Purple rarity    M  Suggestion I'd like to be able to make cards with purple expansion symbols.	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.	Can't edit cards in Safiria    U  Ongoing Bug When using Chromium on Ubuntu 12.04, I cannot edit cards that I have created — instead I get the "We're sorry, but something went wrong" page.	Allow (1) in text in comments    C    A way to temporarily turn off symbol expansion to allow OPENBRACKET 1 CLOSEBRACKET as text in comments without it appearing as a mana symbol
Colour indicator    C  Enhancement DFCs, Kobolds, Transguild Courier and so on now have a colour indicator. We should be able to do that in Multiverse too.	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.	Preview button for card editing    C  Feature It'd be nice if you could preview what a card would look like from the edit page. Particularly if you're trying to trim down the wordiness so that the text doesn't have to shrink so much.	Split and Flip Cards    C  Feature Allow us to create split and flip cards.	Return to previous page after login    C  Enhancement Not sure how feasible this is, but: if you're viewing a card, not signed in, and then you sign in, it'd be nice to return to the card you were viewing rather than be taken to the homepage.
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.	Cockatrice integration    C  Feature Cockatrice is an open-source deckbuilder and gaming table. It supports set import from arbitrary URLs.	Details page for cardset edit guidance    C    Add a special details page title which will get embedded by the side of that cardset's create/edit card form.	Per-user popups with prefs    C    Original content lost to spam attack – sorry. It was something like: 1) Allow users to set a flag saying "I'm happy to receive templating advice". It should default to off. 2) Make an info panel pop up on mouseover of a user name, showing this flag's status.	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?
