Not sure if its a feature request, existing feature, known issue or bug, but the card images come up over the page dialogue. They also persist if another card is selected and need to be actively deselected to be closed.
As they don't seem movable, having persisting images seems redundant. It would seem cool if they could be moved to the side so I could have a few cards open to compare effect etc. In which case, as I'd probably have scrolled from the card title, being able to close the image by clicking on it somewhere would be nice.
Also wondered if the default card sets included should flag off the mage selected (i.e. if I select Warlord, then FM vs W seems a useful default spell set to include).
