Data binding is one of the two highest priority features for the next
feature addition interval, which will not be until after 2.8.0 is
shipped. So yes, some form of DataGrid is likely to make it into Gtk#
at some point.

1) NodeView, Store, and Selection are all attempts to expose the
TreeView API in a C# friendly manner, not custom widget implementations
2) I am NodeStore's author and consulted on NodeView/Selection which are
thin wrappers of their Tree* equivalent. The likelihood of me
maintaining a from-scratch widget that I didn't implement or even
consult on is pretty slim, unless it's really really good code and a
really general-use and compelling widget. Custom widgets are for the
most part outside the scope of Gtk#.

The reality is that this just doesn't work. There have been numerous
experiments in widget aggregation in GNOME from gal to egg. For that
matter, libgnomeui. Most of the general purpose widgetry is already
contained in Gtk#. Do you really want your users to have to download
and install the NPlot widget to be able to use DockToolbar? And do you
really want the developers of DockToolbar to have to synchronize their
release schedule with the developers of WidgetA thru WidgetZ?
We have already put in place the beginnings of what I think makes the
most sense regarding a widget/control repository for Gtk# derived
I think it would be good to turn it into a table with licensing
information available at a glance. As it starts to grow, it can be
categorized by styles of widgets and so on. All it needs is an
I think a referential repository of independently released widget
libraries that can be imported into or referenced by projects makes much
more sense long term than the
