1. Doesn't which-key also provide the
possibility (e.g., on-demand instead of
by timer) to show all currently available
bindings at top level, i.e., not on a
prefix key)?  I thought it had added that
feature at some point.

If it doesn't, then that's another big
difference ("critical", you say) from
KeySee.

2. As for getting the completions in a
buffer that you can access "persistently"
(and, e.g., to search or edit):

There should be a separate, more general
feature for that: be able to "save" the
current contents of `*Completions* (or
another buffer displaying completions) to
another buffer, regardless of what that
completions buffer is showing.

IOW, this shouldn't be only about _key_
completions and descriptions as help.

Icicles provides such a feature (as does
Embark, IIUC).  Emacs should have it.  Hit
a key, enter a destination buffer name (or
just hit RET for a default name).

3. Icicles can also show you complete help
for key completions shown in *Completions*,
in *Help*.  And likewise for any other
kind of completions for which there's a
help description.

Showing help for completions is another
general feature that Emacs should have.
