I actually just sent in a suggestion/support ticket last week but here's what I think would be an improvement:
Right now the page rules system seems like an added feature but I think it should be the heart of the settings system. When a new site is created, it would be logical to just create a default page rule that covers everything like "example.com/*"
Each rule can have a summary of settings as they do now and all the other separate pages can go away. Speed, Caching and ScrapeShield can just be settings for each rule instead of full pages. It'd be a lot faster to manage settings this way and more natural to view a site's settings as a cascading set of rules with their own configuration.
Likewise, Traffic can probably just be made another tab under Firewall.
Traffic actually originally was underneath Firewall, but Traffic will expand to other kinds of traffic/log related data in the future, so we decided to break it out now.
(i.e. this is the 1.0 release...we have a LOT of stuff planned for the next months in various areas)
We're working internally on a number of different ways of how to integrate Page Rules better into the user interface, include a few ideas on these lines.
Forgive me for coming off as a jerk but I think you might be getting phased out of the comments as your site - at least the one pulled from your comment - is not amazingly designed for a UX/UI person.
You're using #666 text on a black background on an almost too-minimal design, which is really hard to read even as someone that doesn't have much trouble in the vision department. Do you have any other sources of work to sell yourself a bit better on the design credibility side? You're also using a heck of a lot of hashtags on the page that aren't even links, what's behind that?
If anyone has a question, feel free to ask me here :)
