Multiverse Feedback: Virtual Booster

Framework    C    Make legend Frames,saga Frames and Splitback or flip transform cards	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.	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.
Images for set symbol/rarity    C  Feature I should allow people to specify images for their set symbol for each rarity, to be used instead of the current "bold letter in a box" if provided.	Split and Flip Cards    C  Feature Allow us to create split and flip cards.	Expand flip card text    C  Bug The expand button doesn't work on flip cards.	No color indicator on moon side    C  Bug of double faced cards.	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.
Support "active" status better    C  Enhancement Currently, the Visual Spoiler includes non-active cards, and the cardlist includes them by default too. I should let cardset owners specify how non-active cards are treated.	Return to dropdowns after saying Custom    C  Enhancement If you select "Custom" in the Supertype or Watermark drop-down lists, that converts the drop-down to a free text entry field; but there's no way to return to the drop-down (apart from refreshing or clicking save-then-edit).	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	Mockups favoured over images    C  Bug In a cardset such as The Oncoming Storm where the default display is set to be the image, there are certain places where the mockup is still used. Most notably the hover tooltip on internal links. I should display an image if one's available and the cardset is configured to prefer images.	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?
