Look for export options that preserve hierarchy, comments, and attachments, not just a flat picture. OPML, Markdown, CSV, and well-documented JSON keep doors open. Batch export and scheduled backups prevent lock-in. When migrations are survivable, you choose based on progress and fit, rather than fear of losing months of hard-won structure and shared understanding.
Reliable local caches and conflict-aware sync let you think on flights, trains, or spotty cafés. Background merges avoid surprise overwrites. Clear indicators show what is saved and what awaits connection. Mobile, tablet, and desktop parity means you can continue confidently everywhere. Offline resilience transforms tools from occasional helpers into constant companions that respect real-life constraints.
Granular permissions, SSO, and audit logs help teams meet internal policies. Encryption at rest and in transit protects sensitive branches. Data residency choices and transparent retention rules ease compliance conversations. Clear incident practices and independent assessments build trust. When security is understandable and verifiable, stakeholders approve faster, and contributors feel safe to share candidly and productively.
