Hi Greg, glad to hear that you were able to find a solution! In Millau, you can create an event-driven action sequence, and set Skuid: Page rendered as the triggering event. This should eliminate the need for the snippets watching for a pageload.
Also note that you can set the scope to listen for this Skuid Page: Rendered event. Choices are “Only This page,” “All active pages,” and “All active pages and Lightning Components.”
And this same Skuid Page: Rendered event-triggered action sequence can trigger other action sequences you might build. In this way, you should be able to have one place you can keep page-load triggered action sequences, and you should also be able to order them in the appropriate order so that the sequences that depend on others being completed won’t run until it’s their turn, so to speak.
