question: catalog.add() seems not change local config.file

Description: 
1. jupyter notebook import the existing catalog.yaml to load all data (works)
2. use catalog.add and save the a new dataframe (works, data in catalog.list() and DF can be found on disk.)
3. check the local config.yaml file, cannot find the item

Continuing earlier convo here.
One of the common ways I've seen users interact is to add them to conf files and access them in jupyter notebooks using `catalog`. 
As catalog objects in notebooks are the final form after resolving a lot of user specific definitions such as paths, credentials, jinja replacements of variables, so in my opinion it's not  best to write/sync to global yaml directly from catalog. 

That said, I see how being able to write config to a temp file would be useful.
If I may ask, how are you adding objects to catalog. I feel like adding each object to catalog manually might be tedious.

Something like this might for individual datasets and specific ones but I'm not confident it'd work for every dataset & will still need cleanup

wow! Totally. this explanation is quite useful.
