it would be nice if the main implementation for sorting and filtering models would enable adding of rows / columsn in the beginning / end. This would be useful to add something like an auto filter row to a model (like in Excel --> auto filter). But this implementation does not enable adding of rows. The only sollution I found (together with the Qt support) was to copy QSortFilterProxyModel and to change the code. But that means, for each new release, I have to check the changes :-(. This would be a helpful feature. Especially, as it is not so easy to write a generic proxy from scartch (QAbstractProxyModel) that does it including filtering (and perhaps sorting). And adding this to the base model is not what I expect. This would be functionality, I would like to be able to add to any model.
What do you think about that?
