If wireframing using current tools is taking up so much of your time then why haven't you set the wheels in motion to invent the tool you want? Sketch up your idea, let someone else code it, and then pay them for the product. Problem solved. Otherwise, it's all just your opinion and HN link bait.

I'm not sure I agree with your opinions about wireframing tools, and I wonder if your frustrations are actually about wireframing or maybe something else altogether related to your projects that you may or may not realize and/or mention in your post.

Coding such a tool yourself or sketching up some UI ideas are probably the two fastest ways to get the wireframing tool you want.
