We'd like to know the name of the layout by internal ID.
So similar to GetFieldName(Field), we'd like to have a GetLayoutName(Layout) functions.
We'd pick the layout from list with layout picker and than internally FileMaker stores ID and we can query current name at any time.
This would allow us to rename the layout and still keep the link internally though ID.
And if we say Go To Layout by name, we can decide for a layout name in script and pass it as text.
