How to save and reopen width of columns in Krusader ?

[petrogromovo]

Hello,
using krusader in Kubuntu 18 in dirs/files listing I always see that opening
Krusader I have to tune width of columns with all columns, as not all columns are visible, like:

I tune width of all columns manually, but after restarting of OS I see my prior
width settings for all columns were lost. If there is a way to tune width all columns once and forever ?

Thanks!
