Adding chapters to podcasts has gotten dramatically simpler over the past couple years, to the point where I think it would be a really nice plus for the premium podcasts (at least the long ones, Bombcast/Beastcast) to have chapters. Nothing too fine grained, even just What You've Been Playing, News, E-mails would suffice for most weeks. When there's specific attention paid to a particular game, it would be nice to have it as its own chapter so if you really have no interest in it you can skip to the next section.
Almost all podcast players also have support for chapters now (even Apple's bare bones Podcast app is getting them in iOS 12), so it would be accessible by most users.
Perhaps this is just an esoteric request from a niche user. Just thought I'd throw it out there as a nice "plus" for being a premium member.
