Code Editor Save icon is always active even when no changes in text content.  Save file icon d (4253162)

After saving some sql, the save diskette icon does not gray out, showing that the latest version was saved. I want to bring back a feature in SQL Nav 5.5.4.

SQL Navigator 5.5.4
1. in the editor window, enter a query
2. Select * from dual;
3. click on the save to file icon
4. now the icon is gray out so you know the query has been save.

SQL Navigator 6.0
1. in the editor window, enter a query
2. Select * from dual;
3. click on the save to file icon
4. The icon is NOT gray out so you don't know if the query has been save yet..
