this is not only a major pain in the ass, but also much much worse than just having a persistent multiline editor window that keeps your code, cursor position and selection intact between executions.

there is simply no comparison here.

Use snippets and just hit the run button for a near-identical experience. There is a keyboard shortcut for it too IIRC
