Lookups: unit types, amenities, tags and categories

Settings → Data → Lookups lists every editable value set: unit types, amenities, furnishing levels, property types, lead sources, lead lost reasons, maintenance categories, expense categories, document types, contact tags. Add, rename (both languages), reorder or archive values; archived values stay on existing records but are hidden from new ones.

Custom fields: add extra fields to properties, units, contacts or leases (text, number, date, list) — they appear in forms, filters, exports and templates as variables.
