Multiverse Feedback: Virtual Booster

Levelers    M  Legendary Feature	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.	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.	Comments on skeleton page    C    If I'm using a skeleton, then it's basically the main landing page for that set for me. Except I have to jump back to the other view to see comments. It would be nice to see a snippet of the last comment on each card; the red/yellow/white comment will take care of letting me find new ones.
Lower case symbols    C    Can we pretty please support ?	Can't Access my Set    C    Well, that's not specifically true. For my Unplaced Cards set, I am unable to access to front page. This means I can't see any new comments on the set. I am, however, able to access the other pages, such as individual cards in the set and the visual spoiler. My other sets seem to be functioning fine.	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.	Cockatrice integration    C  Feature Cockatrice is an open-source deckbuilder and gaming table. It supports set import from arbitrary URLs.	Card history    C    When someone edits a card, they have the ability to comment on their change. I think it would be nice if there was some way to view older editions of a card as well, like on Wikipedia. That way, you could know what I used to have as flavor text here. ;)
Sabotage!    C  – Concern I don't know if cmeister2 is messing around with his own account, or if someone else is sabotaging his work, but his 5 normal cards have become experimental garbly-gook. This could bode unwell for the editable format.	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.	Split and Flip Cards    C  Feature Allow us to create split and flip 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.	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?
