Actually there is a way to do it until the new features come.

You can get the idea by looking at
http://ddaa.net/texmacs/style/tags-0.1.tar.gz

What you need is:

1. A package which defines typesetter function label-func which is a
wrapper over label

2. A conversion program which convert label primitives to label-func
applications.

3. label-func must display its contents when some document variable is
set.

4. optionnaly you may want to set the document variable from the menu.

The package is attached to this mail (it require the tags package
which you can find at the address above, and which is also attached).

Additionnaly, you need to put this to your .TeXmacs/progs/my-init-texmacs.scm

(exec-file "$TEXMACS_PATH/progs" "init-texmacs.scm")
(exec-file "$TEXMACS_HOME_PATH/progs" "showlabel.scm")

The file showlabel.scm is also attached and should be saved in .TeXmacs/progs.

PS: conversion back to normal labels is left as an exercise for the reader.
