no they don't.

I think you wasn't too clear on what is what you wanted, anyway I think it has nothing wrong with having custom columns even for fixed cols, just it was not the initial goal.

Many if you think in the current situation and just changing SetColCount to get custom columns and columns on sync, but now I understand what you want, it would be nice indeed.

As I think it's not just changing a couple of lines, I would like to know what other persons think about this feature, would it be welcomed no not? if there is enough demand we can do it.
