Autocomplete - larger and separate window?

Something that I think could speed up my work a little does not (I think) exist in LibreOffice, or any word processor.

When I am summarizing something on screen 2, and typing to my word processing document on screen 1 (mostly looking at screen 2), I rarely see the autocomplete word pop up before I’m finished typing it. However, if the autocomplete pop up word were larger - or, better, large and in a window on my second screen, I’d probably press return to use it a lot more often…Would this be possible with libreoffice writer?
