The dashboard layout allows for quick navigation of campaigns, leads/opportunities etc without having click through multiple pages or screens just so you can see what needs attention next! It's easy enough that anyone with basic computer knowledge should be able get up-to speed quickly when it comes time do some work here (or send someone else).
I'm not sure if this was an oversight but there are no analytics available anywhere within my account once we have completed our first month / billing cycle - which makes sense given how new they were at launch as far back then goes their history page does show data from all months after initial signup though none before hand? Maybe more detailed reporting would help make things clearer than currently provided by other tools out there such us Google Analytics & Leadpages Dashboard Pro??
