Drupal 8.x

After updating to Drupal 8.3.7 the following error reports when I run update.php :

"Plugin not detected
Panelbutton requires the plugin.js library. Download the plugin from http://ckeditor.com/addon/panelbutton at least version 4.5.6, and place it in the libraries folder (/libraries/panelbutton)"

Plugin is downloaded. However, I can not find a "libraries" folder to put it in...

I have created a custom twig template i.e node--events.html.twig by copying node.html.twig file. (where 'events' is my content type.)

HTML code which has few columns and rows is added to node.html.twig file which displays fine at the front end.

Now I need to load data from the database (instead of hardcoded html data) and want to display at different rows of this new template.

Hello,

This is my first post on Drupal forum. I was looking for answer in Google but I didn't find it.

Question 1:
a) Is there plugin for Drupal that can convert or add AMP version of website.
b) Is it easy to use for beginners (website that i want convert, wasn't made by me)?

Question2: What do you think about automatically generated AMP version of website (eg. small website for local business) is that have any sense if website isn't so much slow and only one reason to do that is SEO?

Thanks in advance for help!

Have Views Content Panes changed names?
I'm only seeing Chaos Tools Views and Chaos Tools Blocks, neither of which seem to act as views displays.
Has the functionality been entirely reworked or has it not been ported?

I am new to drupal and I am trying to build an online newspaper. I want to categorize all of my articles using a 'Sections' taxonomy with tags like 'sports', 'politics' etc. I want to build a page for each section where all the articles with the tag of that particular section are displayed. I want the layout and the UI of each section's homepage to be different. How do I go about achieving that? Also, how can I assign a twig template to a page from site administration interface.
