How to apply default FVS to a tab ?

[jjk]

I am not able to apply any FVS to some tab.
I know how to save FVS of the current tab, even to save it as default but when I switch to the other pane, or when I put the focus in another tab of the same pane, or if I go to one level up, or one level down on the same tab, my columns set and widths are losen.
That is my first question.

So I have the next wish :
manage the columns set of a tab (which columns are visible) and the columns widths by scripting.
Even if there is a satisfactory to my first ask, it would be a great plus to have script commands to manage columns.

TIA

FVS are Folder View Settings. What you can do is check "Remember list settings per tab" in Configuration > Advanced > Miscellaneous and enable it for the desired list properties.
