Our current site view:
I reccomend to install "Admin toolbar" module at first. It's wery helpful module and we will have acess to all configurations pages from toolbar. Click "Extend" link on the top of the page and "install new module" button on the opened page. After that open this link in the new tab https://www.drupal.org/project/admin_toolbar and copy tar.gz link to the latest version for Drupal 8.
Put this link to the "Install from url" field on your Drupal web site and click "Install"
Click "Enable newly added module". Select the module at the opened page and click "Enable"
Now our toolbar has sublings items. It's fast and comfortable to get access to config pages now.
