After using the Sonic-Pi for some time, my experience is that the code editor of Sonic-Pi is a little incomplete in some aspects, such as folding/expanding, find/replace, etc., which is quite necessary in writing/reading Sonic-Pi codes, especially when you’re dealing with quantities of codes.
But anyway Sonic-Pi is definitely a creative and good product for those who want to code music! Thanks to the Sonic-Pi team!
