Hi,
First of all thank you very much for your effort, I really like the 4.5 version. I'm a Quickplay Frontend heavy user, having configured about 50 systems on it, but it's currently unmaintained and I'm liking EO very much.
I'll suggest an idea about the wonderful video support with autoplay you have added: on full collections, videos are always rarer than snapshots, so it would be great if a combined video/snapshot panel could be created, so if the game has a video associated EO plays it, but if there's no video, the screenshot is shown instead.
Also there is another way of enhancing it, like Maximus Arcade frontend does: when you click a game, the snapshot is shown in the panel (as loading the image is faster than loading the video). Then if a video is available, after some timeout (i.e. 1 or 2 seconds) the video starts playing instead of the snapshot. This way something is displayed instantly ant when de video player plugin is loaded, the video starts, without "blank" panel anytime.
Thank you again for the work, I'll surely be watching the development on EO.
