I'm more looking forward to startup screens and pause menu. Bezels and fades aren't necessary to me, more of a nice option to have. For the startup screen, it would be nice to display the platform image with the current game selected logo. Along with the game details such as number of times played and/or last time played. Videos or animations would be great too.
Pause menu, I would like to see a quick way to access a controller button layout image for that system... I.e. n64 button layout translation for my Xbox controller [maybe even have the ability to select it as the background of the pause menu]. Access to save states, manuals & artwork. Ability to view retroachievements for the game you're in. Would also love to be able to have the pause menu mappable to the Xbox home button, as that would be a nice global shortcut for that.
Love all the progress launchbox/bigbox has been making, and even more excited about these new features coming! Thanks.
