There is a 15 second delay between videos on chromecast, it would be nice to change that to 2 seconds or something much shorter. Right now it’s hard coded and there’s no way to change it.
There’s already another feature suggestion discussing an option to change the autoplay countdown duration. I suggest you comment/vote in that thread in order to avoid distracting or cannibalizing votes.
Unless I’m missing some unique aspect of your suggestion, I’ll therefore close this thread as a duplicate.
