Multiverse Feedback: Virtual Booster

New OGW Mana    M  Creature – Eldrazi Devoid (This card has no color). Can someone add the new colorless mana symbol ?	Different card frames    U  Enhancement Stuff like the old frame, PCH planeshifted, and FUT futureshifted.	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.	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.
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. ;)	Completed sets are invisible    C    Not sure what the solution should be here – but it would be nice if finished sets didn't get completely lost and vanish into obscurity; since they would seem to be a good draw for visitors. Currently though, since they have no activity – they're pretty much impossible to find unless you know about them already.	Unusual boosters    C    Options for a cardset to have boosters that don't follow the 10 C / 3 U / 1 R/M distribution, or that ignore rarity altogether. If the idea isn't too crazy, boosters with a number of cards different from 15 is cool, too.	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.	+ / - buttons don't work any more    C    Looks like an update to Chrome's DOM handling has broken them.
Watermarks on cards    C  Feature Let people specify a large image to sit behind the card text, to be a watermark.	View cards before publish    C    It would be nice if there was a button that allowed us to see what the finished card would look like before we create them.	Can't generate a skeleton    C    I get error 500.	From unaddressed page, go to set comments.    C    The unaddressed page shows a list of comments – and you can click to see the discussion. Except when one of the comments is a comment on the cardset – then you just get sent to the cardset front page. It would be nicer if that sent you to /comments	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.
