Thank you for submitting your idea. While we understand the comment, we are not planning to remove this sort button. Maybe alphabetical sort is not useful for users with a large amount of projects but it can help users with 10 or less. Also, switching the sort between most recently visited and most recently created projects has proven useful to a number of users.
you're welcome. 10 projects, divided into two rows, what's there to sort? it's larger number when you need to sort.
