How do I customize the Page Layouts in organizations to include all of the activity options to the right. Currently only an email tab shows and there should be:

• log call
• create task
• add note

When I look in Setup > Object and Fields > Object Manager > Organization > Page Layout



As well, all we can find for adding notes to a record in Lightning is an upload function for files
in Classic it is 'new note' or 'attachment'.

All advice appreciated

I just enabled Lightning for three users in my org, including myself as Administrator. 

When I switch to the Lightning Experience, I get sent to Setup Home. I can't load the main navigation/toolbar. How do I exit setup and start using Lightning?
