Multiverse Feedback: Virtual Booster

New OGW Mana    M  Creature – Eldrazi Devoid (This card has no color). Can someone add the new colorless mana 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.	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.	+ / - buttons don't work any more    C    Looks like an update to Chrome's DOM handling has broken them.
Expanding flip cards    C    I've noticed that when viewing flip cards with a good deal of text, if I try to expand the text, the font size increases but the text box doesn't increase properly. In addition, other fields don't seem to consider it necessary to move, so they cover up the words.	Horizontal cards    C    Is it possible to have cards display horizontally – like plane cards?	Details page for cardset edit guidance    C    Add a special details page title which will get embedded by the side of that cardset's create/edit card form.	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.	OpenID signup and login    C  Feature Web users have too many passwords. Don't make people create a new one: let them use their Google account or other OpenID provider.
My Cards    C  Enhancement It'd be nice to have a global link to My Cards (i.e. ones the current user has created), or My Recent Cards, or something.	Can't generate a skeleton    C    I get error 500.	Rotating images doesn't work    C  Bug The "rotate" link on flip cards should see which of the Image and Mockup tabs is shown, and rotate whichever is showing.	Level-Up Cards    C  Feature Let us have a nice frame for creatures with level up.	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?
