Multiple tabs in the Customize Editor

[Tensibai]

Is this issue related to an issue?.

While learning to author asset, it's great to have a look at another asset for inspiration/see how it should be done.
However switching from an asset to another and more specifically for function it's a bit hard as it makes a lot of clicks to switch.

Describe the outcome you'd like from us

Multiple tabs to switch easily from one function/asset definition to another.

Describe alternatives you've considered

Opening multiple tabs
