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...

TableItem item = variableTable.getItem(variableTable
                .getSelectionIndex());
        String variableName = (String) item.getData();
        IPath variableValue = (IPath) tempPathVariables.get(variableName);
        
        PathVariableDialog dialog = new PathVariableDialog(shell,
                PathVariableDialog.EXISTING_VARIABLE, variableType,
                pathVariableManager, tempPathVariables.keySet());
        dialog.setVariableName(variableName);
        dialog.setVariableValue(variableValue.toOSString());
        dialog.setResource(currentResource);
        
        if (dialog.open() == Window.CANCEL) {
			return;
		}
        
        removedVariableNames.add(variableName);
        tempPathVariables.remove(variableName);
        String newVariableName = dialog.getVariableName();
        IPath newVariableValue = new Path(dialog.getVariableValue());
        
        tempPathVariables.put(newVariableName, newVariableValue);
        
        updateWidgetState(newVariableName);
    }
