Awesome suggestions! You're absolutely right – navigating the Vault with arrows keys/buttons would be a slick improvement. That idea has been floating on my to-do list, and thanks to your nudge, I'll make sure it's locked in for the next update! Regarding the auto-hiding buttons – great minds think alike! That feature is actually implemented. If you move your mouse cursor away from that bottom panel of actions/buttons and give it a second, they should gracefully fade away, giving you an unobstructed view. However, you've just sparked another thought! Maybe the auto-hide should be more responsive – disappearing even when the mouse is just hovering over the panel (unless it's directly over a button). I like it! I'll look into refining that. Thanks for the fantastic feedback!

Great idea! Expect in the next update.
