scene wide keyframing - when?

That's the one feature I need, you know, for doing previs you animate camera and the path of the characters and let their walk clip play... and no parenting those under one animator isn't cool.

 

NAO! click on the red buttons in each track and voila! It's quite nice really but how do I move the keyframes around, you know like the animation window's dopesheet.
Even with those annoying intrack curve editors you can't multiselect across tracks and proper snaping is kind of important.

 

Currently,yYou can edit an Animation Track's Keyframes (Dopesheet-style) in the Animation Window; this editing is parallel to the Timeline Editor. I have made and attached a GIF to show you how it works!

 

Kinda hacky but I guess that'll do for now. It'd be more usable with the animation window's position on the time line and zoom match timeline's
