I want us to hold off on that as well.
I agree that we need a more solid base.
I want people to really have a go with making GUI toolkits in D without the worry about how to do the cross platformy technical things.
Is dlangui a good start on this?
We just don't know what could be done yet and I'm looking forward to finding out.
I think improving dlangide will give us many opportunities for what a good D native GUI library needs.
