Changelog: The Navigator v1.3.0 Release

Alex Mercer — Fri, 06 Nov 2026 12:00:00 GMT

Added & Changed

Modular Feature Toggles: Every major site section (home, about, now, blog, photography, log, tags, contact, contactForm, rss, and llms) can now be toggled on or off in one place. Turning a feature off skips building its pages and automatically removes its menu links, homepage carousel, /log/ filter tab, /tags/ section, sitemap entries, and RSS/AI feed items.
Configurable Root Homepage (defaultHomePage): Any enabled section (such as /blog/, /about/, or /photography/) can now be set as the root / front page instead of the multi-stream overview.
Optional Contact Form: The Formspree message form on /contact/, /about/, and blog articles can now be disabled independently (contactForm: false or an empty endpoint) while keeping email and social links active.
Streamlined Starter Documentation: Simplified the README and Part 1 Setup Guide into a clear, jargon-free tutorial with prominent feature toggle examples.

Changed & Optimized

Instant Hover Page Preloading: Enabled background prefetching on link hover and tap so subsequent pages load instantly.
Zero-JavaScript Layout Refinements: Replaced client-side resizing scripts on /blog/ with modern CSS flexbox layouts for zero layout shifts and smoother scrolling.
Compact Changelog Summaries: Compacted long release logs on /log/ into clean 3-bullet previews with native expand/collapse details.
Accessibility & Motion Polish: Added respect for reduced-motion preferences, improved keyboard and touch tooltip handlers, and unified search-engine structured data.

Dark Mode Surface & Typography Polish: Enhanced contrast across tag badges and navigation pills with clean slate surfaces and warm amber accents for comfortable reading.
