I really like this update because of the "Add Insert" for mixer channel as Macro target

They haven't explained it well but in short, in the macro editor you now have an agrument for "Add insert to selected channel" which lets you select a plugin chain, or plugin/preset. You can then assign this to a keyboard shortcut and load your favourite plugin(s) that way or using the Remote app (like I'm doing).

Next will hopefully come the same for Instruments.
