Can one have a string without safe formatting?
It’s quite limiting to not be able to use things like \n, in a string.
Plasmic should free us up, not limit us 
I just realised that for the case I posted, it’s enough to use control: 'large', in order to have Studio handling newlines better.
I am not sure what other situations would benefit from having a safe formatting disabled, but there might be more.
You can also right-click and select “dynamic expression”, and write a javascript string that includes \n etc
