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.	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.	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.	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. ;)
Sort/show by Rarity buttons in Spoiler    C    It's probably been brought up and considered before, but I'd love the ability to show/hide cards of a given rarity in the Visual Spoiler, if not all relevant tabs.	Unshrink small card text    C  Feature On cards with too much text, it can be hard to read their rules text. Add a button on the card's page to expand the text up to readable size (and stretch the card frame out of proportion).	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.	Customise print size    C    Could we have cards printable at custom resolution? I dunno if you can set css width:4cm or whether it needs to be done with dpi calculations or what, but it would be nice to be able to get slightly more cards on a page at a slightly smaller than normal size (or support other games where the cards are slightly different sizes)	"Hide flavour text" button    C  Enhancement SFletcher suggests a switch to make flavor text visible/invisible. This would allow us to look at a card's rules text alone for reviewing clutter.
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	Colour indicator    C  Enhancement DFCs, Kobolds, Transguild Courier and so on now have a colour indicator. We should be able to do that in Multiverse too.	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.	Gold planeswalkers in IE    C  Bug In Internet Explorer, starting loyalty doesn't show up on multicoloured planeswalkers.	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?
