Playground: reset storage #309
Description
The playground persists the modification to the account storage, which I think is very useful (although I don't know if it's intentional or not). For example, running this multiple times will keep increasing the first storage slot.
But if I want to start over with an untouched storage, I then have to refresh the page (which makes me lose the code I was writing).
I believe a simple reset button should be enough for this use case. Alternatively, this could be a switch to either preserve the previous storage or not.
