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.	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.	Can't find this page    C    In the end I resorted to google, which sent me to toothycat via which I got here... So yeah. "feedback" isn't the name I searched for, I searched of "Bugs and Features" (and variants thereof) none of which found this page. Should be more locatable.
Ability to print a selection of cards    C	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.	General Discussion Set    C  Suggestion I think a set titled "General Discussion" started by you, and open to everyone would be a good idea. Individual topics can be started by creating a new card.	Framework    C    Make legend Frames,saga Frames and Splitback or flip transform cards	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.
My cardset kinda broke    C  Bug The main page of my "Shiny Umbreon's Unmade Cards" set (id=477) is all messed up and the pics are not showing. Pages of individual cards work fine, though.	Allow easier card links in comments    C  Enhancement The ability to link to other custom cards with (((triple parens))) could be enhanced. Allow (((C1234))) to link card ID 1234, and/or uniquely-named cards in other cardsets.	Split cards on cardset front page    C  Bug On a cardset front page, split cards can turn up twice in the "recently modified cards" list. There are also scattered occasions when clicking the highlight / unhighlight / etc buttons on that page don't work for comments on split cards.	Mockups favoured over images    C  Bug In a cardset such as The Oncoming Storm where the default display is set to be the image, there are certain places where the mockup is still used. Most notably the hover tooltip on internal links. I should display an image if one's available and the cardset is configured to prefer images.	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?
