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.	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.	Recent Updates not always up-to-date    C  – Bug The Recent Updates seem to have a caching problem in general right now: I often have to refresh/force refresh the page to see any new activity.
Allow Custom Symbols    C  Feature Allow us to specify small symbols/icons to be included on cards. If we were creating our own mana symbols like snow or Phyrexian mana , at the moment we couldn't have those images display on cards at all.	Cards have descriptions?    C    Could cards have a way to select a single comment as the cards description / rules clarification / whatever, to be shown in the various grid views?	Lower case symbols    C    Can we pretty please support ?	"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.	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.
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.	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.	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.	Same card codes    C    An option for cards fighting for the same slot. Not sure how the skeleton would/should display it, though. Same card code may go against how you already coded things, but an alternative could be something like "CL05b", idk.	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.
