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.	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.	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.
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.	Warn if about to lose unposted comment    C  Enhancement If you've typed a bunch of text in a comment box, but then click "Edit card" or some other link, the comment isn't posted. I could make Multiverse warn you about the unposted comment, like Stack Exchange sites do.	Recent comments area doesn't refresh    C    At the bottom of a card set's front page, the recent comments area doesn't refresh to show more recent comments. This is probably another cacheing issue.	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.	Cockatrice integration    C  Feature Cockatrice is an open-source deckbuilder and gaming table. It supports set import from arbitrary URLs.
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.	CSV Export/Import of split/flip cards    C  Bug This just doesn't work at all. I should figure out a way to make it work.	Printer friendly Test Set    C  Feature It would be nice to be able to print out black and white cards that still look kinda like cards – no filled borders. Like the Wizards playtest slips we see from time to time.	Card art on tokens looks horrible    C  Bug	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?
