This is monumentally stupid design. When I mark a comment as spam, it's for two reasons:
- To mark it as training data for a spam filter, and
- To send it somewhere so no one has to look at it.
Now, Reason #1 is apparently a joke, because I haven't seen Blogger filter out spam in years, but hey, maybe they will, one of these days. But at least I didn't have to look at it anymore in the old interface. But the new interface shows ALL comments as a default, and you have to manually select "Published" comments each time you use the interface, so basically there's zero reason to even have a "Mark As Spam" feature. It's obviously better to just delete spam manually.
There may be other major flaws, but I haven't used every single feature yet. I have other dislikes, but those aren't objectively worse features, just subjective experiences. I've only noticed one improvement, but it's something that only matters to someone like me who uses StackEdit for posting on Blogger, so I can't say I'd recommend the new interface to anyone else.
