maintain most-recently-used custom-selection/visib

[pschlie]

As although a custom-selection/visibility script may be added to the

script list; it would be very nice if the most-recently-used scripts

were automatically available via a menu selection list to make selecting

frequently used scripts easier (and semi-custom-selection/visibilty

scripts are automatically added and named by their selection criteria,

without having to explicitly save them.)

I would just like the previous selection to reappear the next time I invoke the custom-selection/visibilty command. But what you ask for would be a bigger improvement.
