Quite happy with how the page/component lifecycle log messages are coming along as part of my push to get the new stateful components over the line in Kitten¹.
This should make it very easy to ensure that things are happening as you think they are and to conceptualise the behaviour of your stateful component hierarchies. (You can also use stateless components, of course, as is the currently documented workflow.)

Finally got my paws on a physical CD of Switched-On-Bach by Wendy Carlos, which she apparently REALLY doesn’t want copied. I guess that explains why there is no digital version.
The disk format is a rococo tangle. iTunes can play the music, but it cannot import from the disk. It cannot understand whatever arcane trick was used to construct it. I had to copy the AIFF files manually and import the copies, then add metadata manually.
