Multiverse Feedback: Virtual Booster

My cardset kinda broke    C  Bug The main page of my "Shiny Umbreon's Unmade Cards" set (id=477) is all messed up and the pics are not showing. Pages of individual cards work fine, though.	Collaboration with MtGNexus    R    I've been contacted by someone who wondered whether a partnership between MTGNexus and magicmultiverse is in the cards. Excerpt of the message to the right.	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.
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	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.	Per-user popups with prefs    C    Original content lost to spam attack – sorry. It was something like: 1) Allow users to set a flag saying "I'm happy to receive templating advice". It should default to off. 2) Make an info panel pop up on mouseover of a user name, showing this flag's status.	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.	Split/Flip card ease-of-use    C    The way it works now, with the frame selection opening a new selection box, seems to have an extra click or two. Instead, why isn't the box that says normal/split/flip always present? It will usually not matter, except when someone creates an alternate-frame card, when it become easier.
Application Errors    C  Error Frequently getting these Application Errors. On some days it's really bad. Loading a cardset or page requires many tries. If working on a new card, it could mislead you to resubmit several times, thus creating multiple copies of the same card. I assume this server runs on ASP.NET because I only ever see these errors on ASP served pages. Quite often, actually, not just this site.	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.	Details page for cardset edit guidance    C    Add a special details page title which will get embedded by the side of that cardset's create/edit card form.	Split and Flip Cards    C  Feature Allow us to create split and flip cards.	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?
