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...

editSelectedVariable();
            }
        });
        editButton.setFont(font);
        setButtonLayoutData(editButton);
        removeButton = new Button(groupComponent, SWT.PUSH);
        removeButton.setText(IDEWorkbenchMessages.PathVariablesBlock_removeVariableButton);
        removeButton.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent e) {
                removeSelectedVariables();
            }
        });
        removeButton.setFont(font);
        setButtonLayoutData(removeButton);
    }
