Either change the VIEW settings "default file" behavior to include when a user selects a "new layout" or add a new setting called "new layout file".
From a user perspective I think the "layout parameters" settings are a little confusing. It is confusing to alter a setting, then choose a "new" VIEW layout and have that setting disappear. I think many users would enjoy being able to control the "new" VIEW layout as well as the VIEW layout that loads upon program load.
Yes, a general solution for all customers with all individual wishes is the same concept we already have in REPORT: Loading a layout file when "New layout" is selected.
