One pattern that may help (without heavy re-org) is to treat those snippets as first-class items with a stable home, and only link them out:
reply- keep an “inbox / snippets” note (or a single folder) where every orphan snippet goes
- give each snippet a short, searchable handle (one line title)
- add 1–2 lightweight links: related topics, and optionally “why it matters / when I’d need this”
Then when you’re in a top-level doc, you can embed/query “snippets linked to this topic” instead of trying to decide the perfect location for each one.
In your case, are those “things to remember” mostly time-bound (follow up, renew, schedule), or more like evergreen reference (commands, ideas, reminders)?
