Photoshop: Displacement Filter Overhaul. Live preview of Displacement.

After Effects allows for the use of one layer from the same project to be used as a displacement map for another, with live manipulation of the values being displaced. Can we get some love in Photoshop for something similar? Even just removing the additional step of saving a seperate PSD before you have to guess what amount of pixels you are displacing the object(because there's no live preview for this filter) would make this less arduous. Live preview of the displacement would be a godsend.

Unfortunately I am not optimistic on this as I suspect very few Photoshop users use the Displace Filter even halfway regularly ...

Well, they might, if it was more powerful, flexible, and had live preview.

I see it as having as much of an application as puppet-warp or perspective tools. I see fairly regular posts about "How do I warp a logo over a shirt?" or "How do I wrap a texture on a face?" that invariably devolve into "Well, there's the Displacement map, but I don't have 40 min to describe how to use it, so here's a link to a youtube video..."
In a perfect world, the interface would be similar to the liquify tool with the option to apply a texture or layer mask as the displacement map, then a realtime preview with a brush to change the map.

Heck, you could piggy-back onto the existing liquify tool dialog and distort the liquify mesh with an optional "diplacement map" section with the option to use a particular layer or alpha channel and pixel displacement adjustements. This would have the added benefit of making the displacement map feature more visible and available to consumers. Plus it's sexy marketing to say "Liquify Tool now included pixel-level micro adjustments through height mapping!"
Adobe, YOU'RE WELCOME!

I wonder if this would have to compete for resources with Warp-improvements requested in at leat one other thread, though, as both might be considered as having similar applications.

Or the map could be editable the way masks are. Its thumbnail could appear to the right of the mask thumbnail. (Granted, it would take some more realtime processing power; masks and blending modes do a 1-to-1 pixel operation for every x,y position, while this would be  a 1-pixel-to-multiple-pixels operation from the original image to the image warped by the displacement map.) Allowing it to be an editable smart object could be even better. (Heck, why can't masks be smart objects?) You could have a toolbar appear while its selected (with options like softness to smooth out discrete bump levels). It could be RGB, and on the toolbar you'd select which channel effected X displacement and which effected Y displacement.
