Multiverse Feedback: Virtual Booster

Hybrid written as "R/G" gives gold frame    R    If someone enters hybrid mana in a card's mana cost field without putting parens or braces around it (i.e. writes "3R/G" or "1R/GR/G", it's correctly interpreted as hybrid, but the frame autodetection code treats it as gold.	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.	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.	Ability to print a selection of cards    C
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.	My cardset kinda broke    C  Bug The main page of my "Shiny Umbreon's Unmade Cards" set (id=477) is all messed up and the pics are not showing. Pages of individual cards work fine, though.	Level-Up Cards    C  Feature Let us have a nice frame for creatures with level up.	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.	Application Errors    C  Error Frequently getting these Application Errors. On some days it's really bad. Loading a cardset or page requires many tries. If working on a new card, it could mislead you to resubmit several times, thus creating multiple copies of the same card. I assume this server runs on ASP.NET because I only ever see these errors on ASP served pages. Quite often, actually, not just this site.
Watermarks on cards    C  Feature Let people specify a large image to sit behind the card text, to be a watermark.	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.	Cropping roll-over image    C  Bug When the tooltip image is larger than usual, e.g. the default for a cardset is to prefer images to mock-ups, the roll-over displays the card image, but (at least for me) the right edge of the card gets cut off, removing the P/T, loyalty, and/or mana cost.	Printable?    C  Bug Whenever I click on the the "Printable" button in the Visual Spoiler, I get an error message, in both Chrome and IE.	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.
