Debugger enhancement request

[BruceH]

When single-stepping through a program, please can we have the debugger automatically show the values of all variables mentioned on the current line and the value of any variable set on the preceding line?

Code:

e.g:
...
b := sin(a);     // Debugger shows variable a
c := ln(b);      // Debugger shows b and a (b at the top, a below it)
...

At the moment I find myself continually removing one variable and adding another to the display area.
