How to create a pick-list?

It seems that whenever I trigger the Macro, the window always falls upon the app window I'm using.

Is there any way to free it so that it can appear elsewhere?

Not using native AppleScript or JXA.
But you could do this using this excellent AppleScript Script Library by Shane Stanley:
Dialog Toolkit Plus v1.0.1 and Dialog Toolkit v2.0.3.

But that would require a major rewrite of the AppleScript.

You could also use Custom HTML Prompt action (KM Wiki), or MACRO: Spotlight Search Prompt by @DanThomas.
