Can I customize the learning plan according to my needs?

You can easily customize the learning plan in the "Plan" tab. There you will find settings related to the number of cards per day, so you can determine how much time daily learning will take you. You will also check how long it will take you to complete the entire course. Additionally, in the "Calendar," you can disable specific days if you know that you won't have time for learning on those days - there will be no repetitions to work through. Both options are available in the "Statistics" menu.
