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.	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.	Leveler Creatures    C    Personally, I'd like to see something that would create the "leveler" creatures from Rise of the Eldrazi card format. Hope that makes sense. :D
Level-Up Cards    C  Feature Let us have a nice frame for creatures with level up.	Ability to print a selection of cards    C	Order by submitter    C    Was looking for the cards I'd created in design challenge; doesn't seem to be any easy way to do that right now.	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	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.
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	Auto-detect existing card names    C  Feature It'd be nice to automatically tell people when they're specifying a card name that's already been used by Wizards.	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.	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?
