ok. I did that and I had questions below.

1. I see that standard home template has a header and two equal columns below the header with a full height side column. Can we choose a blank template and add components to it. Or is there a way i can hide the side column.

2. Chatter feed and publisher components added to home page. But I can't see any chatter posts i made where as i can see them from chatter tab.

3. Recommendations Component _ I don't see any lightning documentation for this component. Even though i added this to the home page i could not see it.

4. what is the best approach to have the classic side bar components in lightning ?

Appreciate your help on this.
