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.
https://github.com/VK/dash-lumino-components
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
https://github.com/golden-layout/golden-layout
or react FlexLayout
https://github.com/caplin/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!
