Multiverse Feedback: Virtual Booster

Proxy    M    It would be a nice feature to be able to print proxy cards to play test with	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.	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.	Print without header/footer    C    The "Cardlist | Visual spoiler | Export | Booster | Comments | Recent activity Upcoming releases New card | Import data | Unaddressed" box still appears on printable links. Which pushes cards onto more pages than needed.
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).	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.	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.	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.	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)
Watermarks on cards    C  Feature Let people specify a large image to sit behind the card text, to be a watermark.	Multiple cardset admins    C  Feature There's currently no way to allow a few people to edit a cardset unless you allow all signed-in users to do so. There should be.	Gold planeswalkers in IE    C  Bug In Internet Explorer, starting loyalty doesn't show up on multicoloured planeswalkers.	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.	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?
