What is "Slim UI" in Sololearn and why it is used?

Question

In coding section, on the right side three dots menu, an item appears bottom of the "Save as" is "Slim UI" and it is not checked.

So why it is used and what is meant by this?

Answer 1

You can't enabled slim ui without saving the code. Once you save the code you can enable it.

The upvotes , name of author and time etc that appears at top of ui gets shifted to bottom so you can get some space where you are writing code(on top)
That's all. //not much useful
