Lightweight Gantt Chart Plugin - Visual project management for kintone with drag & drop

Hey Product Hunt! 👋 I'm Takumi, a kintone plugin developer. **The Problem:** Many kintone users struggle with project timeline visualization. The standard list view works for data entry, but when you need to see task dependencies, schedules, and progress at a glance — you're stuck exporting to Excel or using external tools. **The Solution:** I built Lightweight Gantt Chart to bring visual project management directly into kintone. No more context switching, no more manual syncing. Just drag, drop, and you're done. **Key Features:** ✓ Drag-and-drop task rescheduling ✓ Progress bars with percentage display ✓ Color-coded status (Completed/In Progress/Delayed/Not Started) ✓ 3 view modes: Day, Week, Month ✓ Weekend highlighting for better planning ✓ Bilingual: English & Japanese **Built with care:** - Uses only official kintone APIs (no risky DOM manipulation) - Easy setup — no coding required - Subscription-based pricing for continuous updates and support I'd love to hear your feedback! What features would make this even more useful for your team? 📹 Watch the demo: https://youtu.be/K2_GaV6cDmw
