Hmm, I must have missed. You never said that you want to implement this-and-that
in Emacs, and explained why and how. What you said was you consider the separation
"useful", which is considerably more weaker statement.
Are you actually planning on implementing locals/arg separation in Emacs in
observable timeframe?

Uhm, this is very subjective statement (though you seem to use Totalview as
example regularly). Looking on the screenshot, I am not impressed.

I am not aware how marketing/management/design works at that company, so I
cannot comment on this.

I disagree. Sensible frontend interface is only possible if we (or I) understand
specific use cases that are supported, and how they are supposed, as opposed to
working from requests to add some information to some command.
