Multiverse Feedback: Virtual Booster

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.	Expansion symbols    R  Suggestion I'd like to be able to show the expansion symbol.	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.	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.
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.	Same card codes    C    An option for cards fighting for the same slot. Not sure how the skeleton would/should display it, though. Same card code may go against how you already coded things, but an alternative could be something like "CL05b", idk.	Innistrad Skeleton    C    In the Generate Skeleton Examples, It would be nice to have Innistrad appear as one of the examples. It's one of the few modern stand-alone sets that doesn't have something funky going on with the numbers.	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.	Cockatrice integration    C  Feature Cockatrice is an open-source deckbuilder and gaming table. It supports set import from arbitrary URLs.
Lower case symbols    C    Can we pretty please support ?	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	Sort/show by Rarity buttons in Spoiler    C    It's probably been brought up and considered before, but I'd love the ability to show/hide cards of a given rarity in the Visual Spoiler, if not all relevant tabs.	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.	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?
