GUI Event Loop integration
Description
GUI libraries such as napari rely on IPython's opt-in integration with GUI event loops to render and respond to user interactions.
We currently have no support for integrating with GUI event loops.
Suggested solution
Provide integrations with GUI event loops, and let third-party libraries start these event loops.
Alternative
No response

I love what you've built with marimo.
One of the reasons I'm holding back from switching over fully to marimo is a feature like this. I use napari currently and can't seem to launch a new qt session from a marimo cell:
napari.view_image(img_array)
doesn't really do anything.
Is this feature on the roadmap?
not sure where this is at currently, but had a discussion with some colleagues and napari is a critical part of their workflow. for our adoption of marimo, it'd have to support GUI event loop integration
