I have to say I”m still a bit confused since soft introduced the keying panel, the first thought I had was:
Why a keying panel instead of a new way of displaying parameters on custom property pages!!!
I think PPGs are really flexible, you can easily make a keying panel out of them and you can display more informations taking advantage of the PPGLayout, I”m still hoping something like that will happens in the future, I don”t see any reason why not.

Apart from that, the keying panel is a great tool for keying, really handy, just a problem on multiselection is not allowing us to use it in our pipeline here in Lionhead.
It seems that when a few objects are selected and the timeline is scrubbed, xsi kind of slow down till it almost stop working.
We”ve been told this has something to do with the good old bottleneck of processing parameters in scene.

Well I hope to find the best workflow soon, thank you for this article Luc, it will help a lot!
