I appreciate the feedback on the beta posts. This combined format works for early betas when we're unaware of feature sets, but it's harder to maintain when there are separate features for each beta that people want to discuss.
Another issue is that beta posts are prepared ahead of time so we can let MR readers know right away when a beta comes out without delaying, and betas don't always come out all together.
I'll combo when I can, but for the most part beta articles will continue to be separate. When there are no new features in a beta as is often the case with tvOS, we do have a feature for making sure it doesn't take up much space on the front page, which we always use. I've also been comboing tvOS and iOS when possible.
