I'm using the default theme / default view. (semi-required when playing with Beta releases... lol)
I only had a few minutes to play with it, but I mostly saw just clear logos (large). Some had a background image (fan art category maybe? I have no idea), but most didn't. Didn't see a single video play. This is probably my biggest gripe about BigBox after all these years of using it. I am still 100% clueless about what media categories its pulling from without firing up a theme editor and digging around. Can you put that in the GUI? (This theme uses the following media categories...... and have it read the actual theme configuration to pull those values out).
Oh here's an idea - show the media categories (dynamically based on currently selected theme / view), and then have an option to flag those in BB "Download this media category next time Launchbox is run" (For current platform or all platforms)
And even though my cab is 100% keyboard setup (IPac encoder), it was showing "Press (Gamepad) Button" - which... is sub optimal at best. I wish it would use button labels instead (Press Select - the function, not the button or key currently assigned to Select - for example).
Also, the after some time in BigBox screensaver move, the Windows screen saver kicked in. As far as I can recall, BigBox has never allowed the Windows screensaver to activate while in BB attract mode. But BB screensaver mode appears to allow Windows screensaver mode to activate. (I just turned off WIndows screensaver to solve that). Probably an edge case, but I figured it was worth mentioning.
