webplus…I’m not sure I know enough to answer your question, but that sounds similar (if not exactly) like the QooQee Blog Widget for Muse.
Perhaps check out the features list and descriptions on this website to see if this is what you mean: https://www.qooqee.com/adobe-muse-widgets/muse-blog-cms.
The QooQee Blog is loaded on my host server, so there is an initial upload and activation step in order to use the Blog Widget placed & styled in Muse and accessed/managed within a browser.
The way it works is, you place & style 3 widgets in the Muse editor: 1) a post-list widget 2) a post widget, 3) a category widget…and then upload that Muse file to the host server, and then you initiate it and configure settings to activate the Admin Panel in the browser, and then you make/edit/manage individual posts within a browser using your live website…hope that helps to explain it!
You can even drop in a 3rd party tracker with social icon links like AddThis: https://www.addthis.com/share-buttons-for-amp/
Looking forward to see what you are making…Yay!
