Adventure Mode: Quality of life UI/input requests

[trunksbomb]

Is your feature request related to a problem? Please describe.
Adventure mode is fun, but there are some common quality of life features and UI improvements that would make the experience better.

Describe the solution you'd like

1. Escape should always bring you either completely out of a screen or one step back. Some screens (the shops, for example) use Enter to leave the shop and Escape does nothing on that screen
2. Dialog boxes should be closable with Escape or Enter (or space?). On multiple choice dialog boxes, this is possible using the arrow keys to navigate first to a button, then hitting Enter. On single button dialogs, though, the arrow keys do not highlight a button and the button is not highlighted by default
3. A preview of the battlefield card granted by a piece of equipment would be nice when hovering that equipment in the shop, so I can make an informed decision about what items I want to buy
4. There's no "held button prevention" when pressing Escape to bring up the main menu. If you press Escape to bring up the menu but don't let go immediately, then letting go of Escape will exit the menu. This can cause you to unexpectedly close the menu if you held the button for too long.
5. Better UI clarity in the deck management screen. Some specifics:
   1. The color and type filter button backgrounds are a black gradient background on a dark blue background - a lighter color or even a light color border would help emphasize these buttons
   2. Likewise, the text highlight on the search filter is hard to see, so it wasn't obvious to me at first that re-focusing the search box was automatically highlighting the text I put in there
   3. Search button appears to always be grayed out and clicking does nothing - only Enter while focused on search box or unfocusing the search box (by clicking somewhere else) will apply your typed search term
   4. After typing a search term and hitting Enter, search box is no longer focused and requires clicking it again to type
   5. Enter on the Number Pad does not submit your search term - only the "real" Enter key does
   6. I'm not intimately familiar with the card type icons in MtG, A simple text label popup when hovering the filter icons would be neat here
   7. Escape does not exit this screen

Describe alternatives you've considered
I currently don't have those QOL features, which seems to be my alternative now.
