Please enable Esc and Enter keys in all the places possible. Some places I can think of:
1) Logging in. After typing the password, Enter should be recognised instead of mandating the mouse click
2) From the Old Mil, Esc should bring us back to Main menu
3) When a deck is constructed, pressing Esc should cancel the deck creation
4) Where ever we have "Back to Menu", please recognise Esc key.
[QoL not involving Enter/Esc]
1) During deck construction, I should be able to remove a card that was added without needing to go to the left panel and scroll down and find the card to remove. Either right click or even Space should be allowed to remove a card from the main deck screen.
