Angus, I certainly don't deserve this compliment, but I greatly appreciate it. [C'mon, I had a minimal contribution in src/graphics. And for the LyX core, I just humbly (sometimes even enthusiastically) follow the leader: Andrà is putting most the work and ideas...] > I can even follow the code.

Exactly. > So, how do you envisage keeping the data valid? I don't know if that is desirable. Maybe we need some simple structs after all. I don't know how the Cursor class will behave in this respect. As it is based in paroffsets, it seems that it can lose track if for instance one eliminates one paragraph before (and/or up in the hierarchy)... maybe it's indeed something that needs discussion. The distributed cursor has the advantage that it never gets invalidated except when we eliminate the paragraph it's in. Regards, Alfredo
