Extrude > Preview

Hello,

I know there are multiple way for extrude, but I need to question[the reason of] the little popup window for "Cancel/Accept" when using the "Extrude > Preview".
One of the annoying things is the fact it[the "cancel/accept" popup] likes to appear at the top left of screen. Why have a visual tool that then places a "Cancel/accept" just about as far away as it possibly can from the actual default visual tools dialog? I know I can press "Escape/enter" to perform the same function as that little popup, but would the options it gives not be better incorporated into the visual tools dialog?

What are your thoughts on this?

In my opinion the button should appear in the settings.

I`m no friend of popups anyways. The hunt for the close command/buttons is always a workflow killer. No matter how decent you try to integrate it.
