Multiverse Feedback: Virtual Booster

My Cards    C  Enhancement It'd be nice to have a global link to My Cards (i.e. ones the current user has created), or My Recent Cards, or something.	Levelers    M  Legendary Feature	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.	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.	Different card frames    U  Enhancement Stuff like the old frame, PCH planeshifted, and FUT futureshifted.
Watermarks on cards    C  Feature Let people specify a large image to sit behind the card text, to be a watermark.	Tags for easily searching themes    C    Imagine I have a minitheme without a keyword (because the text isn't consistent, like AVR's "loner" theme). It's awfully hard to keep track of them normally. If you could put tags, like "Loner Monoblack Sacrifice" to indicate it fits the loner theme, that it supports monoblack strategies, and that it supports a sacrifice theme, for example, it would be a lot easier to keep track of the different themes you have. Of course, this kinda implies the cardlist should have filters already. :P	Ability to print a selection of cards    C	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.	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.
Can't Access my Set    C    Well, that's not specifically true. For my Unplaced Cards set, I am unable to access to front page. This means I can't see any new comments on the set. I am, however, able to access the other pages, such as individual cards in the set and the visual spoiler. My other sets seem to be functioning fine.	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.	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.	Preview button for card editing    C  Feature It'd be nice if you could preview what a card would look like from the edit page. Particularly if you're trying to trim down the wordiness so that the text doesn't have to shrink so much.	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?
