Snippets: does not ask to save if modified, but it should ask me

If I edit an snippets, the tab shows the asterisk star *
but on closing I am not asked to save my changes,
they are just saved without my acknowledge, which is bad in my opinion.

This way I can easily damage my snippets.

Please let editing a snippets behave like any other document too, and
ask the user if he wants to save his modification or not.

 
Thank you for making EmEditor.
