Save interface when starting a new analysis on same Dataframe

[FadyCoding]

Is your feature request related to a problem? Please describe.
When we start a new analysis with the same data frame slightly modified, for example after deleting biased data, we lose some information from the previous analysis.

Describe the solution you'd like

What could be saved in this case are :

• The widgets positions within the window.
• The widgets parameters.
• Launch the drawings, if possible and not too costly.

Describe alternatives you've considered

You will notice that this feature works for few widgets like the "Data distribution" widget.

Additional context
Add any other context or screenshots about the feature request here.

Saving the widgets parameters and positions within the window already work when exiting an analysis (need to be properly exited)

Launch the drawing on start is already an issue : #161

you can also save a layout : https://debiai.irt-systemx.fr/dashboard/layouts/

Closing because already supported
