If I click on 'Deck', the last chosen deck is displayed, but without any information of which 'Slot' number.
If I open my deck, make changes, and then like to save my changes, I do not know which 'Slot' number
I am currently into.

So, if I am at the deck building screen, it should show the current 'Slot' number of my deck. I then would know
which 'Slot' I am currently changing. That would make it much easier to choose which 'Slot' I might overwrite.
