I'm about to make a lot of changes to the main learning area and don't want to make stupid decision, so thought to get ideas from here first.

Around 5 days ago I've made a post showing the first version of my app, the idea is to allowing the user to make their own outline and have my system create a youtube playlist.

Since them I made a lot of changes, now I would like to know how to improve the user learning experience for you, does the UI look inviting and feel comfortable to use ?, what should change ? what should stay ? what do you think ?.
