How two obtain two identical Atom installations

I have two Mac machine each with an Atom installation with several packages to create a “python notebook like” user experience (most important is Hydrogen).

Even though I think I’ve installed the same packages at the same levels the two editors behave differently especially in the syntax highlight/suggestions (PEP8 etc) and colum wrap.

I like my iMac’s installation behaviour more than my Macbook’s.

Is there a way to recreate my Imac installation in an identical way on the Macbook (packages, setting, whatever ?).

Not sure this is imporant but the two MacOS levels are not the same Sierra vs Catalina and not 100% sure the Python levels are identical (3.x for sure on both).

Thank you very much.
