Feature: Duplicate solutions
You're working on a Python Morsels exercise, you got the base problem working and now you'd like to attempt the first bonus. But you want to edit your code into something new without losing your current working code. You can now duplicate your solution!
If you hover over a solution a copy icon will appear (it looks like two pieces of paper, one on top of the other). Click it to duplicate your current solutiion.
