What should you consider when prioritizing information and features across screens on a product?

Based on solutions and ideas from "Can you make it more prominent?" stakeholder phenomenon I decided to list out and prioritize each of the features on each screen in the product.

Turned out it's not so simple, some screens would have much as 50 information blocks or features (also some features can be ranked at the same level). After each of these have been prioritized, how would we use design to convey this priority in a single screen?

Things I'm considering right now

• typography size and style
• colors
• isolation and grouping
• flow of user actions
• placement (this is the least that is flexible without a major redesign)

What other design elements could be used and how would you use them?

We are also looking how features that span across in the funnel will be more important in some screens than others.

How should we get about using the takeaways from feature prioritization to reflect on improvement on the UI design of product?
