I don't think the basic model should know about the visual lines. We

discussed

that for a while, but in the end that's purely a view on the basic model.

If such behaviour will be at view simple Cursor>>moveUp/moveDown will never

work right from user perspective. So why you need cursor at text model

which will never reflect state of visual cursor at screen?

it depends, I think the model should not take the view into account.
First we implement the cursor movement as simple as possible, and that is
for now on the model-base.

If it will work properly or not depends on the view implementation.

To me text model should completly represent what user see at text view.

Otherwise why you call it model? Otherwise it is just raw data like Text in

current TextMorph

Model IS the raw base model, the view is what you see, that are definitely
two different things.
For instance where would you deal with hyphenation? dynamic layouts?

I don't think they belong in the model and I think we should stick to
existing implementation schemes (M VC) and existing implementations
like Cocoa...
