Tangential feedback on the Playground / on-boarding experience

[LDMFD]

Hi, not sure this belongs here - would just like to pass feedback that the Playground appears to be unusable if it doesn't support having more than one instance open at a time.

For someone learning the platform, the ability to open samples alongside my own app is essential.

All that said, thanks for the great product! I am not deterred by this UX hiccup, in fact it is a subtle way to get people using the big brother zed validate 🙃
