All for this, just be as clear as possible when asking for the live letter, last thing want is SE to go overboard and remove more important confirmation windows. For example Extract can easily have its removed but Retrieve should keep its confirmation window.

I'd also like Retrieve materia be renamed to Remove materia, the 1st time I saw Extract and Retrieve I was nervous which did what, it's a 1 time thing but it is needlessly named too similar to each other.
