Super Secret Technque Uncovered!
Here's a 'secret' that might help in many cases...
Use a Blank page. You can create a layout named Blank tablename and delete all of the fields. It helps, I assume, to use the basic layout in 12.
Filemaker has been hiding many layout choice by using a selection dialog designed for a cell phone instead of a modern computer so you can also use the down arrow (what a waste of time, huh) to locate the Blank layout option.
I've found using an empty layout has saved a lot of time in various script steps, especially ones with related fields but the file is not available.
Other times instead of using a Form field with tons of portals to loop through records, the blank layout zips right through while I can still use some functions such as GTTR as the table is related to this table, not the layout.
Ocassional some oddball feature will provoke a bug with this idea, but very seldom.
If you have been using Form layouts with a dozen portals on them or table layouts with 95 fields on them to loop through records, I think you will find this speeds up that script a bit...
And when you step through layouts to do stuff, using the blank layout for each table can save the redraw time, etc.
