First up: the inserted menu items still do not stick and stay in Actions from session to session.
The filters menu is gone for good. Only effects are now available. Arrow heads are exactly the same trash as always available only as an effect. Same with offset path. Someone's not going to like that one. Once you expand the offset path effect, the original path disappears. So useful isn't it. But if you're drawing clowns for a living it might work for you.
Not sure what that implies: how can you drag if the child layer is not
shown?
I cannot drag an object from the "Foreground" layer to the "Type" layer in the Layers panel. This bug has existed in 11, 12, and 13. Probably 9 and 10, too.
I don't bother with sublayers because it complicates my particular workflow unnecessarily.
But I checked and the behavior is exactly the same. I don't think it's a bug though. It looks like it was designed that way so you don't get the art confused, otherwise I don't think there would be that little negative stop sign showing (red circle with a slash)
Multiple artboards are a somewhat PITA though. Maybe I just have to get used to doing it their way instead of the way I think it should work.
Bug.
