v1.3.1

Release Notes

🛠️ Improvements & Fixes

Editor Tabs: Unique Identification & Independence

• Resolved Tab Merge Issues: Fixed a bug where opening multiple prompt files or creating new tabs could result in duplicate IDs, causing tabs to merge or lose independence.
• Improved Tab Creation: Now, each new tab gets a truly unique identifier—even when opening multiple prompts at once or rapidly creating/removing tabs—ensuring that tabs remain isolated and fully independent.
• Bulk Operations Stability: Enhanced tab management code to increment tab IDs correctly, preventing accidental overwrites or UI glitches during bulk open/close actions.

Technical Details

• Refactored the Tabs component’s tab ID generation logic, switching from tabs.length to a dedicated nextTabId state tracker. This change ensures unique tab IDs regardless of the tab creation/removal sequence.
• Code improvements in tab creation, prompt loading, and bulk operations, ensuring reliable user experience when managing many prompts.

Key Commits:

• Fix tab ID generation to ensure uniqueness by @copilot-swe-agent, co-authored by @rawveg
• Fix Editor Tabs Merge and Independence Issues (PR #30)

---

🚀 Upgrade Guidance

• No manual migration needed—these improvements affect only the UI and internal logic for managing open prompt tabs.
• If you experienced issues with tabs merging or losing content previously, simply update to v1.3.1 for a seamless, reliable experience.
