It would be nice to have single show/hide all comments toggle button in Calc.
That's requested in Bug 84837 comment18. Show/hide all comments can be done via Sheet-Cell Comments-Show/Hide all comments (seperately) but one toggle button on toolbar would be practical like writer and impress (uno:ShowAnnotations).
it sounds reasonable
