Display list : where to define the default values

How to define the default values for the display list, like hereby:


When clicking on the "select columns to display" we found a "reset" button:


How to change the default values?
I am trying to make a default display list not showing the fields we just have chosen to hide

Hum, I am looking for a workaround:
1) I tried to make a "user model", changing the display list fields and copying that user to create a new one
=> does not work, I got the default display for the new one.

2) When the "technical manuel" will exists, do you plan to give explanation about how the "static" configuration is made so that admin could "statically modify it" ?
Or do I need to investigate "alone" to find where the static parameters are store (php or db)?

3) Asking every user to make the modifications appears to be a real drawback to adoption .
How do you usually handle that?

Thank your for your answer.

OK, I will wait until then so.

Do you plan to release it:
a) before the end of this year (2017)
b) during 2018
c) later
