Is there a way to disable Metadata and Preview both opening?

This is not currently possible but definitely something worth considering as a future enhancement. I've forwarded your feedback to our product team.

Joonas Linkola We would like both to open every time always when clicking a document.  So maybe a toggle multiple ways.
