Visual deck list view

[jumpinjackie]

Now that we've figured out how to overlay text on top of images, we can now implement a visual deck list view that is not absolutely cluttered.

• Support SKU-based grid view
• Support text-based view (to replace the original "View Deck" command)
• Nice to have: Support "stack of cards" view grouped by mana value with lands/SB in separate columns
• Toggle to allow switching between consolidated and SKU-based views. In SKU-based view, enable SKU editing/transfer commands available in other tabs
• Implement a variant of "Add New" command that adds new cards directly to this deck without having to add it to a collection or un-parented first
• Implement a "Add Existing" command that allows one to search for and add SKUs from a container to this deck. If the amount added is not the full quantity provided by the SKU, auto-split the SKU and transfer the split SKU directly to this deck, otherwise transfer that SKU to this deck.
