Drupal 8.x

We are moving to Drupal for an internal web site. I am responsible for a separate project to stand up a file repository consisting of Word documents, videos, etc. My project is moving faster, so I want to create my repository in a way that will be easier to move into Drupal if we are eventually asked to do so. My questions are:

My first steps in Drupal 8

For theme reason i prefer that users may have the 'edit link'  directly into the node instead of menu tabs. In D7 it was very simple, just inserted in node--type.tpl.php this php

if (node_access('update', $nid , $user))
{
echo "<div class='div-edit-node' title='Edit'><p class = 'edit-node'>".l('Edit', 'node/'.$nid.'/edit')."</p></div>";

But how to in Drupal 8 ?

Thanks for help

You are running on a system where PHP is compiled or limited to using 32-bit integers. This will limit the range of dates and timestamps to the years 1901-2038... 

Hello,

I just wish to know if we can enable "number of unique views" of a content type, so that each node under the specific content type will be tracked.

Thank you. 

Hello. I am new to Drupal. I have Drupal 8 installed and Webform seems like an easy way to create web forms. There is an addon to Webform to send the user to PayPal after they submit the form called Webform PayPal. However, Webform PayPal seems to only be for Drupal 7. Since I have Drupal 8, what would be the easiest way to work with PayPal using Webform? After the user fills out my form, I want them to have the option to make a payment with PayPal. I have a specific email address of the PayPal account that I want the payment to go to.
