Some users don't like the fact that editors are reused if they are not "pinned" (e.g. #61569).
I know how to pin an editor by double-clicking but I had a hard time to find the corresponding setting enablePreview because "preview" isn't something I can relate to "pinning".

IMO "enablePreview" is a less-than-ideal name (but it is probably too late to change this).
I suggest to at least mention the concept "pinned" in the description of enablePreview.

If I search for "pinned" in settings I find only this (which appears to be completely bogus):
