Hello, it would be useful to have a page 'Table of Contents' on a ArcGIS Hub Site Page (as a preconfigured layout widget card).
In some use cases we are interested in having all the information on a single page (not multiple pages), but have no way for the user to easily navigate other than scrolling down the page.
In an attempt to make my own Table of contents, at the moment there is no way to automatically link to headings (i.e., h1 or Banner) in a single page, but there is a way to link to gallery cards (if enable sharing is on), which can be embedded in buttons in a text card, or HTML banchors. After publishing I captured the links to the cards (Share this card option below each gallery), and was able to use calcite tiles (or buttons) to link to the shared gallery cards. This is a useful workaround to jump a user to a certain section, but it jumps below the headings. A disadvantage is that the section must have a gallery card for this to work, or HTML skills to use anchors.

Clicking on one of the buttons above in the page, jumps the user down to the gallery
