ALL great ideas, Lisa!

Thanks, Denise!

Good! I find that good writers are often good readers, so they almost automatically check off good writing boxes. It's usually beginners who struggle with this.
Thanks for the comment!

Sounds like a good system. Thanks for commenting!

I don't repeat the things which haven't changed.

Any other setting information comes somewhere in the first paragraphs, before the reader would ask themselves where or when they are.

It is as brief and specific as I can make it; in back and forth scenes, only the character name part of the header will change; the reader knows time has passed.

After the first few scenes of the first book, a reader knows the system, and the details have faded into the background, except that they know I will keep them in the loop with anything they need to know. I create the header in Scrivener to keep myself oriented while writing.

Jacqueline, unfair or not, it does help when a reader can remember things. But a lot of us (putting my hand up) read to enjoy and relax. I do a lot of heavily detailed, non-fiction research work where I have to pay focused attention in my day job so, me having to track down a fictional character or a previous scene or jump to a new place without really remembering where I've been, really could make me quit reading. I hate to admit it -- I don't usually read complicated fiction. At least, not when I have so little down time. Give me something that does
Thanks for the post!

Exactly! Good point!
