Multiverse Feedback: Virtual Booster

Purple rarity    M  Suggestion I'd like to be able to make cards with purple expansion symbols.	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.	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.
Skeleton generation is broken    C  Bug "Generate skeleton" gives an error for all cardsets. I think line 295 of cardset needs fixing.	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.	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.	Card backgrounds on opera    C    Probably not a high priority, but using opera (11.51), the background colour for lands and multi-colour cards is bright cyan.	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.
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.	More control over search results    C  Enhancement Sometimes people want more or different columns in their search results. I should make assorted columns visible with a checkbox-type toggle, like on the cardlist.	Sealed Pool    C    You know how you can make a booster? It would be useful to make six at once, plus order them by color. cough Useful for playtesting cough	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.	More features for advanced search    B    Can you please give more features for searching cards on the advanced search page? I'd like features that allow us to search by mana cost and colors of the cards. These features haven't been added yet, but it would definitely help a lot if we can search according to mana cost, converted mana cost and colors because I'd like to see all the WUBRG cards in this website, for example.
