Customizing the card or the pipeline columns in list view should save globally. I went back n forth with support for two weeks just to find out it doesn't save by default. We thought it was a bug. It seems when you edit it, it should save globally for all users or at least even for yourself, but apparently it doesn't do that either.

From developers: "Customization on the card is browser & system-specific. It is not saved in the backend so customization settings on one system won't be shown on other systems."

This is useful for specific industries that always view a list/card a specific way. I'm not even able to do this for my clients by logging in as them! It won't work since it's just browser specific. There is also no indication of this in the UI, so it seems like a bug.
