Jun 1, 2026June 2026 monthly summary for sinfin/folio highlights two targeted improvements in live collaboration and editor UX, delivering measurable business value with minimal disruption. The team implemented Collaborative Editing Presence with a new API path to clear the console URL on leave, reducing stale session warnings and avoiding full-page reloads. A second change fixed the Atom Editing overlay to prevent clipping in overflow containers, ensuring the Done/Close controls remain accessible across browsers. These changes demonstrate solid API design, client-server coordination, and cross-browser UI reliability while improving user experience in collaborative workflows.

May 1, 2026May 2026 monthly summary for sinfin/folio: Delivered batch operation UX enhancements to prevent data loss during batch saves/uploads; generalized batch prompts across all file types; improved in-flight state handling via Stimulus events; and localized Czech admin UI confirmation to formal address. This work reduces risk of missed edits during long-running uploads and aligns prompts across file types and locales. Key outcomes include more reliable batch edits, clearer user guidance, and greater consistency with UI language. Technologies involved: Stimulus-based UI state, Folio::UppyComponent integration, S3 persistence coordination, and localization/globalization practices.

Apr 1, 2026April 2026: Delivered three features in sinfin/folio focused on data integrity, searchability, and editor UX, underpinned by robust migration safety and testing against large production data. Key outcomes include Slug Indexing and Safe Migrations for File Slugs (unique index with a guard for removing the old index, validated on production dump with 323k files and 42 duplicate slug groups), CMS Tags-Based File Search to improve file discovery, and Special Characters Popup in the Console with autosave nil-handling fixes. Additional robustness improvements cover non-blank value preservation during console batch form updates and migration guards for pg_dump restores. Business impact: reduced deployment risk, faster, more reliable file search, and a smoother content-editing experience for users.

Jul 1, 2025July 2025 monthly summary for sinfin/folio: Focused on reliability and performance of media processing. Key work includes elevating the ElevenLabs transcription pipeline to produce robust VTT subtitles with direct SRT handling, enhanced retry/backoff for API/signing issues, reliable saving and validation, and support for re-running/restarting stuck processing. Also optimized thumbnail extraction timing for longer videos by using a fixed 10-second snapshot (reducing FFmpeg seeks, improving perceived load time). Results show improved subtitle quality and stability, faster processing for long videos, and clearer UI feedback. Key commits include: ElevenLabs transcription updates (242eb875...; eb41b4d1...; aab4b087...; a8259891...; 6807e69f...), and Video Thumbnail Optimization (375bfa8b...).
