The statusbar at the bottom of a document window has a tooltip which in the case of unsaved changes says (in US English), “The document has been modified. Double-click to save the document.” But this is not true: a single click is enough to cause the document to be saved. This needs to be changed, probably in other locales as well (I didn’t try to find out).
I reproduce from LO 22.214.171.124 235ab8a-3802056-4a8fed3-2d66ea8-e241b80

Thank you for the report,
It will be available in LO 5.4.0.
