Webtools addons
Webtools is all about tools to enhance your website management workflow in Strapi. At it's core, it will keep a register of all the URLs on your website, using those to uniquely identify the different pages. This is a functionality that can easily be built upon by other plugins who also expect Strapi to have a register of URLs. Think of a sitemap, a menu, dynamic links, redirects etc.
To enhance Webtools in a modular way, the core plugin allows addons to be registered to build upon it's functionalities. Addons are in Strapi terms just standalone plugins, but have @pluginpal/webtools-core as a peer dependency. You will have to install each addon as you would normally install a plugin in to Strapi.
