Multiverse Feedback: Virtual Booster

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.	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.	Caching a bit too much    C  Bug Cardset front pages, cardlists, skeletons and visual spoilers cache a bit too much: 1) The admin line of the set views box may be shown or hidden incorrectly 2) Comments don't show up on cardset front page
View cards before publish    C    It would be nice if there was a button that allowed us to see what the finished card would look like before we create them.	General Discussion Set    C  Suggestion I think a set titled "General Discussion" started by you, and open to everyone would be a good idea. Individual topics can be started by creating a new card.	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.	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.	Move cards between cardsets    C  Feature It'd be nice if we could move cards between cardsets we own. At the moment you have to delete it from one and create it in the other, which loses the edit history and comments.
Completed sets are invisible    C    Not sure what the solution should be here – but it would be nice if finished sets didn't get completely lost and vanish into obscurity; since they would seem to be a good draw for visitors. Currently though, since they have no activity – they're pretty much impossible to find unless you know about them already.	Skeleton generation is broken    C  Bug "Generate skeleton" gives an error for all cardsets. I think line 295 of cardset needs fixing.	Ability to see past user posts    C    It would be pretty cool if there was an option to see all of the posts I have made in the past so I can go check where I commented rather than having to remember everywhere I made a comment.	Warn if about to lose unposted comment    C  Enhancement If you've typed a bunch of text in a comment box, but then click "Edit card" or some other link, the comment isn't posted. I could make Multiverse warn you about the unposted comment, like Stack Exchange sites do.	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?
