Currently floating images specified using the VML shapes are imported as non-floating, for example:
<v:shape id="_x0000_s1026" type="#_x0000_t75" style="height:180.25pt;margin-left:62.25pt;margin-top:1.65pt;position:absolute;width:180.25pt;z-index:251658240" o:preferrelative="t">
<v:imagedata r:id="rId4" />
Right click image > text wrapping > more layout options > text wrapping tab
Word supports "Largest Only" but RichTextBox only has both, left, and right.
In MS Word there are several options available in the Advanced Find dialog that are not available in the RichTextBox, the two most requested by our users are "Match case" and "Find whole words only".
