Bug 300846 Add "Resolve Values" switch to Path Variables property page
HEAD Table showing path variables for a resource has 3 columns: Name, Value and Resolved Value. Given the fact that values are rather long the third column is hardly visible. My suggestion is to remove the third column and add a switch to resolve variables in the second column. I'll put up a mockup in a minute...

        return data;

     * 
     * @param enabled the new enabled state of the group's widgets

    public void setEnabled(boolean enabled) {
        if (variableTable != null && !variableTable.isDisposed()) {
            variableLabel.setEnabled(enabled);
            variableTable.setEnabled(enabled);
            addButton.setEnabled(enabled);
            if (enabled) {
				updateEnabledState();

                editButton.setEnabled(enabled);
                removeButton.setEnabled(enabled);
            }
        }
    }
