I followed this guy: https://www.youtube.com/watch?v=-As4BF_O7dQ&t=118s basically as you,it is a TODO list (TATA!).. I know its very complex to use,but you get to figure it out by yourself KAPPA:
- type anything you want in the bottom blue box
- and either you press enter or (+) button to submit.
- to delete something click on it.
