Winter' 16 is Here : A New, Modern, Intelligent User Experience
Yes, Winter' 16 is here and this time salesforce mostly focussed on lauching their new & intelligent UI with Lightning hence making good user experience. It does not support everything right now hence there is an option to go back to Salesforce Classic UI. By going through different objects, you will see that it jumps to classic view automatically for non supportive objects/feature.
UI is cool & easy to use though it will take some time to get used to it. Below are some screenshots for this:
Enable Lightning UI
You just need to enable it from a Quick link 'Lightning Experience' in Sidebar:
Open new Lightning UI
A beautiful loading page will open when you open Lightning UI through link under your name.
Loading Page
Home
A home page will load with some dashboards & assistant with cool tabs at the left.
.
Apps Menu
Account Pages
Pages(Account page in this example) will look like below:
Chatter
Global Search
Layout Editor

Object Manager
Salesforce removes all elements releated to standard objects from sidebar and added them to Object Manager which will take care of all layouts, fields, recordTypes etc. for all standard & custom objects.
