The UI of the Code Review Board is getting cluttered. Many different kinds of elements yield a suboptimal experience: I see little icons, big buttons, blue links, tiny expander triangles, and text instructions in arbitrary places. Also, the UI is not optimized for the most common use cases/value streams:

1) Create a review, add revisions, add reviewers, done.
2) Open a review, examine each file and make comments, done.
3) Open a review, read comments, open files to consider making changes, reply to comments, add new revisions, done.

Recommend a GUI expert to tweak the UI.
