Single-page app with routing using React and Redux

Hello to Frontend Mentor community! This is my solution for "Entertainment web app" challenge. I use data fetching from npoint.io, so is's a 'live' responsive web-site. You are able to navigate the sections, add and remove bookmarks, search content. This is the first time I have implemented Redux for the global state managment and React Router for creating internal paths. I'll really appreciate any comments and advices how to improve my code and architecture of the app.
