Heya. First, I'll note I have a pretty big collection in LaunchBox, and it's always ran a little bit slow until that performance optimization a few betas back - now I can scroll through my platform libraries pretty smoothly either in LaunchBox or in the BigBox mode. Reporting a positive success there. (Win10 with my LaunchBox/collection on SSDs, 7,000 titles.)
Now for my greedy suggestion. I really like adding music/movies to each file in BigBox, but I was wondering if there was a way to do that with platforms (and the "front page" of BigBox mode) as well. Example: You select Nintendo 64 in the scroll menu, and then you can have a general N64 trailer or whatever playing.
Having that (with an option for a default soundtrack to play in the background while navigating BigBox until you select whatever) would make for more of an arcade experience, IMO.
Unless this is already doable to some degree. Then I'm blind.
Much obliged on the program in general, I've messed with a lot of different frontends for years and this has been the best by far.
