Favorites Tab or Save for Later Option

Creating a "favorite" or "heart" or save for later tab would be a useful options when exploring the text. For example, it is great that the text gives a plethora of support and materials, but it is often overwhelming when sifting through all the content. By adding a favorites button, it will create a separate list to return to before finalizing plans. Often I forget where things I find useful are located unless I am actively using them in the moment. This would add another layer of accessibility for educators.
