[Wish]_Cancel button in Advanced Query Editor

[Wish]_Cancel button in Advanced Query Editor

  
Once you open an Advanced Query Editor, it's not possible to close it without saving changes. A Cancel button would be nice.
Hi Tiago,

I think that for the moment the workaround is Ctrl-Z and then close. Ctrl-Z reverts the advanced query to what it was when it was opened.
Cheers,
André
