As a digital designer I’m actually insulted that Adobe is investing time, staff and money in creating a product to make it easier for print designers (I’m guessing this is the goal seen as it’s InDesign inspired) to create web pages.
If you want to help web designers then invest time and money in Fireworks or a true Fireworks sucessor (NOT created with Adobe Air).
I would have said “Make Photoshop not suck for UI work” but it would require changes at a fundamental level so there is no point.
