This may have changed with the advent of 2.0/Qt5, can't recall if it was mentioned. But I can say that in Windows Portable v 1.48 the Home key moves the insertion point to the absolute beginning of the current line (ie what's displayed), irrespective of beautify or tags.
But with 2.14 the Home key positions the insertion point to the absolute beginning of the displayed line on overflow lines and to inside first tag '<' on the first line.
My preference would be as per 1.48, incidentally that's what you get with Sigil.
