This is an interesting concept. It looks great and the Adaptable theme is another stellar option for Moodle! We have got such talent pouring into the design and layout of Moodle.
I think I might be in the minority on this when I say I am not sold on this as being good for our learners.
Our needs are much different coming from a K-12 background. We are very much concerned about workflow and making things obvious for users as to where to go and what to do. This idea makes it infinitely more confusing and harder to process what the user is to accomplish on the homepage. As more elements are added to the initial pages it only adds to the cognitive load a user must overcome to complete a task.
Our feedback shows that less is more and the themes I create for our site reflect this. When a user arrives at our Moodle site we want it to look pretty but not distract from the call to action.
When a user hits the homepage the call to action is to login. We implemented a full screen background and login form front and center. Logged in homepage call to action is get to your course materials or enroll in a course. We implemented the My courses dropdown as well as the icon navigation and search bar to help streamline finding and enrolling in course. In Pioneer theme the Icons and Searchbar can be made to appear front and center in the content area of the page as well as in the top navigation bar.
I realize this isn't the reality for everyone but we are very concerned about workflow and cognitive load on a user.
Moodle is a tool. Hailing from Dearborn the hometown of Henry Ford, we know a thing or two about complex tools used to build cars. With some tools it is not apparent what purpose they serve or how to use them due to the complexity and multiple moving parts. Unlike a hammer, whose purpose is to hit things and the design makes it obvious. We want Moodle to be a hammer - a nice looking hammer whose purpose and function is obvious. Anything else might be distracting and increase the cognitive load to accomplish the task at hand... learning.
That might be to simplistic of a response but the sentiment of getting a more concise workflow and call to action is conveyed.
