I had a quick look at the demo and it looks great, however I don't think it's easier to use.
You claim that you grouped similiar functionalities together but I disagree.
For example, sales related maintenance are in current FA under "sales",whereas you moved them to "setup".
One can see that all the "maintenance" functionalities are similar and now grouped together.
I see that the "sales" functionalities, are similar and should be grouped together (as it is in FA).
For example, I add a new customer when I need it : ie I'm trying to process an order and realize that the customer
doesn't exists. I'm already on the "sales" page and from there I just click on "customer" to create a new customer (1 click).
With the new GUI, I have to click "Sales" (to open the menu), click on "Customers" , wait for the page to load, then click on "new customer", that's 3 click + 1 page load vs 1 click (for the old version). I don't see that as an improvement.
In fact, the way functionalities are grouped at the moment in FA it precisely the reason why I chosed initially to use FA.
I could find things straight, without having ever used the software. The "new" design is more like FA's compitors design which I didn't like at all.
Also, I use the executive theme, which displays all the submenus of a page. I can reach everything in 2 click (select page if not the current one, click on functionality) and if I'm on the wrong page I can see. With the new theme, you are 3 click away of everything and you have to backtrack if the first 2 clicks where wrong. I don't think this correspond to the latest UI principles.
Finally, I'm still waiting for some way of hooking the GUI so textcart could work without having to patch FA.
To summarize, I agree that FA looks old and needs to be pimped up, the proposed UI looks great, but I don't see it as an improvement and hope it won't be merged in the core as it is.
