I'm interested, but some of the ideas you have seem a little too unsuckless
(i'll cover what i think in a mo)
Keep in mind, I'm not trying to be Uriel, this is constructive criticism.

An editor isn't supposed to do any of this, these should really be in
a different programs.
If we could embed things (like XEmbed), in curses, it'd be great.
That's what multiple
terminals are for.

Again, not strictly an editor feature. Static call graphs can be generated
by an external program and from that images or documents can be viewed
with the editor.

Unless your code is all bunched in one huge file, you know what you're
looking for.
Just use a search function? Or call ctags and filter the output to a terminal,
say if you wanted a function list.

Call a separate program to do this (ctags), rather than reinvent.

A scripting feature, maybe, but why follow vim? What about something like
Lua, or even shell scripts (and thus any scripting language)?

External program to generate markup, so you could write javadoc-esque
comments, and get this external program to create your man pages
or whatever. Not an editor feature.

I'd be interested in how to implement this, perhaps using mmap to read
huge files? Or is this what's done already?

The main feature I'd look for would be to filter text through an
external program
and replace the filtered text with the external program's output.
I believe vim has this with

Possibly a visual mode, like vim's would be nice, specifically column-based.

I am a fan of vi key bindings, but just because we are doesn't mean we
stick to it.
We could use /etc/inputrc and whatever else to use the user's
preferred bindings,
and perhaps even have mouse support, similar to what sam/acme use, to keep the
plan9 fanboys happy.

Cheers, Rob.
