I think I know what you're talking about.  It seems to me the question
breaks down in to two parts.

First is the ability to, as you say, stretch or shrink a selection of
keyframes so the range of time they take up is longer/shorter then the
original timing of the keyframes.  I think this is already possible in the
action editor.  Select a bunch of keyframes then scale it using "s".  The
current frame serves as the center of this scaling so you'll want to make
sure your current frame is the frame you want to scale from.

The second part is the part about grouping different tracks together inside
the action editor.  I suppose this could be helpful if you have a model with
hundreds of bones which you need to organize.  For instance, say you can
have groups for the arm, leg, face, etc.

But I have a feeling this is not what you're looking for.  I think what
you're looking for is an "onion skinning" like system similar to what's
available with Character Studio in 3DS Max.  But this is actually layering
and blending of discreet animations clips on top of each other, kind of like
an editor for actions which are layered on top of other actions which may or
may not share keyframes for same set of bones.  That is to say, a "group of
tracks" inside the action editor wouldn't be able have one bone belong to
more then one group where as an "action layering system" would have
keyframes for a bone in "action 01" which blends/overrides with keyframes
for the same bone in "action 02".

As far as I know this kind of functionality is not available in Blender
yet.(Someone please correct me if they knows this to be incorrect because I
would love to know. :D)  This kind of functionality would certainly be a
useful one but it's probably a pretty involved project if someone wanted to
tackle it.
