Move message: move search window from top right corner to center of screen/app

The Problem

When invoking the move message dialog (e.g. via ‘v’ shortcut with Gmail keys) the search window is in the upper right corner. Other MacOS apps (native Spotlight and Postbox mail client) show this in the center of the screen (or app) with a larger font. From a UI perspective this appears to be much better.

Proposed Solution

As a user I’d like to have a config option that would move the dialogue to the center of the screen and give it a more MacOS native feel.
