Why is there no "Practice" option in Grasshopper PC?

Recently, I decided to start using Grasshopper on my laptop. But I noticed that the Practice feature isn’t in the site. Is there any particular reason as to why? I don’t quite understand why it wouldn’t be there. I’m sure the devs have their reasons, I just want to know.

I’ve also sent Email to Grasshopper a lot of times and used the “Feedback” option in the app for particular suggestions or bug reports, but it has been months since I sent them and still haven’t gotten a reply. It’s not like I am that upset about it but I hope the devs would at least reply or something. Anyway, in another topic, I’ve encountered a problem so I’ll be posting it.
