The XML sitemap module creates a sitemap that conforms to the sitemaps.org specification. This helps search engines to more intelligently crawl a website and keep their results up to date.

The sitemap created by the module can be automatically submitted to Ask, Google, Bing (formerly Windows Live Search), and Yahoo! search engines.

The module also comes with several submodules that can add sitemap links for content, menu items, taxonomy terms, and user profiles.

Menu Trail by Path allows the breadcrumb to pick up the trail from the url path of the node as opposed to relying on the menu.  

For large sites this is a game changer.  No longer do you need to burden the menu with disabled menu items in order to have the right breadcrumb.

Menu Trail By Path sets the active-trail on menu items according to the current url.

This module allows site builders to create node with their custom nid. If the node with given nid is already exist a message will occur that "Nid already exists".

For Drupal 10 the custom_nid/custom_nid.info file needs updating with:

• core_version_requirement: ^8 || ^9 || ^10

This is also advised by the Drupal Project Update Bot:

This combines the two modules, JS Injector and CSS Injector, into a single module for simplicity.

As described from those modules, this functions the same. This module is definitely not a replacement for full-fledged theming, but it provides site administrators with a quick and easy way of tweaking things without diving into full-fledged theme hacking.
