+# Build Custom Views
+
+Custom views are saved filters for recurring questions.
+
+## Good View Candidates
+
+- Active projects.
+- People without a recent follow-up.
+- Drafts ready for review.
+- Notes changed this week.
+- Events in a date range.
+
+## View Definition
+
+Saved views live as files in the vault. They describe filters, sorting, and visible columns using structured data.
+
+## Filters
+
+Custom views can use nested conditions, similar to Notion or Airtable filter groups. Combine `all` and `any` logic when a view needs to answer a more precise question than a single field filter can express.
+
+Date filters support dynamic natural-language values such as `today`, `yesterday`, or `one week ago`. Use these for views that should keep moving over time, such as recent work, stale follow-ups, or upcoming events.
+
+## Design The Question First
+
+Before creating a view, write the question it answers. A good view is not "all fields with all filters"; it is a focused lens.
