Complex layout manager

Thanks so much for developing Dash! It’s awesome!

I would like to ask if anyone can work on the very interesting porting of Lumino to Dash.
Unfortunately, the package doesn’t seem mature yet (theming, saving/loading layout), but it looks very promising.

There are also interesting alternatives, such as Golden Layout
or react FlexLayout

The introduction of these packages into Dash would allow to make very complex dashboards.
The best, it will be to put it togheter with other packages, like bootstrap/material/mantine components.
I am aiming to the UI layout of VScode or codesandbox .

THANK YOU in advance for your work, simply outstanding!
