@Cutter - “most people sort content by system this way” I’d have to argue the opposite. Most people I’ve talked to that use RetroArch, at least on Windows, are running a frontend. Personally, I’ve never once used the playlist, database, or favorites features. I was very pleased in a recent update when I was able to remove them from the F1 menu.
I’m not saying either way is ‘better’ by any means, just that this is going to be pretty helpful for a lot of users who do things the other way. Plus it’s not like this negates the possibility for other solutions down the line.
Although, I’ve got to ask, if your games are not organized by system in your library… how are they organized? I can’t think of another way to do it. I’m just curious.
