Did you try function
TRichView.SearchText(s: String; SrchOptions: TRVSearchOptions): Boolean; ?

Sergey, do you intend to support Aspell (0.60)?

Does richview support Aspell new version (0.60)?

Insert "The Borland Developer Studio IDE provides" with tag=1 when user do something with the text that splits it in two, RichView automatically copys the original tag to the new items. So in the end, doesn't matter in how many items your original item was divided because all of them will heve tag=1

My suggestion was a RVItem that floats not only images...

Maybe a RVFloatItem, that can encapsulate one or more RVItems and float.
It would work like like a <DIV style="float: left;"> in HTML/CSS.

Maybe this other topic can help you:

Try
rve.SaveRVFToStream(Stream,false);
