Save the value of "Specify poll interval" into the SQL Developer into the properties.

Writing the value the user entered into the properties file would be helpful so he/she wouldn't need to keep reentering that value every time the app comes up. Also, if we could just write that value in a property value, the app would only need to load it so no need to enter it every time.

Yes this would be very useful. It's super annoying having to enter it every time I start Sql Developer.
