automatic “in selection” box-enabling to be at a lower threshold
As an addendum: The problem with a lower threshold is that many users want to be able to select two or so lines of text, and search the rest of the document for those same lines. That is possible now… but if the threshold were made too short, it might frustrate that use case.
It’s hard to make everybody happy at the same time with software design decisions.
