From a secret laboratory... (automation editor patch)

[zonkmachine]

I have a feeling this feature might turn up in the next release.
From the developer mailing list:

There's lots of neat stuff going on in and around the mailing list

Anyway, this is certainly a welcome addition and I hope it will be included in the next release. It'll be especially nice if the vector-mode automation is "sample-exact", ie. smooth, the same way LFO controllers are. That'd be great, especially for volume/amp and filter automations.
