How to Structure this App?

We (The Milk Mob) publish a weekly blog about breastfeeding which includes a “lactfact”, which is a summary of the post. The lactfacts are in their own div with an id of “lactfact”, for example,
We are going to create an app to display the lactfacts as a list. It will have the capability to keep track of what has been read and to mark favorites – similar to the science news app.
Is it possible to pull the contents of the based on their ID or do I need to list the lactfacts separately for the app?
I am new to Thunkable but not new to coding – would it be inappropriate to ask for a suggestion for the basic structure of this app? I can study up on the components if I know which ones to look at.
Thanks much.
