UI Improvement - viewing card upgrades

[bn]

I'm loving the game so far! One minor suggestion would be to improve the UI around viewing upgrades. I factor in a card's future state when deciding whether to take it or not, and checking upgrades at the moment is a little painful.

On card selection screens, store, etc you have to right click a card and then tick view upgrade. It took me a while just to realise this feature was even there. If you want to do this for multiple cards you have to dismiss the modal and then repeat.

Lightweight suggestion for a fix - add a 'view upgrades' button on the card selection screens, which launches the existing enlarged card view modal, but with the 'view upgrade' tickbox automatically selected. Add prev/next arrows to the modal so that we can quickly scroll through all the available cards.
