Onion skinning is now available in v1.4.01+! It is actually called “Ghosting” and is accessed via the Ghosting button just above the dopesheet. The core of our vision for this feature is there, though it is very new and may see some minor tweaks. This is a powerful feature that has many uses. We will make a tutorial video in the next day or two detailing its usage. Enjoy!
