DevKnife Update 1.2.0
In version 1.2.0 of DevKnife, I’ve added two powerful new tools — a Markdown editor and a structured data converter — along with several quality-of-life improvements and important fixes. This update makes DevKnife even more versatile, helping you work more efficiently across different formats and everyday developer tasks.
Markdown Editor
The new Markdown editor lets you write and preview Markdown directly inside DevKnife. It’s great for quick notes, README snippets, or experimenting with Markdown formatting — a simple, distraction-free way to work with Markdown right within the app.

Structured Data Converter
The structured data converter is a brand‑new tool that helps you convert between JSON, XML, YAML, TOML, and CSV formats. It’s perfect for developers who work with APIs, configuration files, or data exports. Just paste your data, choose the output format, and DevKnife handles the rest.

Spotlight Integration
The WHOIS tool now supports a handy Spotlight shortcut. Just type “whois” in macOS Spotlight and press Enter — DevKnife will open with a domain input dialog, ready for your query. After you enter a domain, the app will display the WHOIS information instantly, making it faster than ever to look up domain details.

Alongside the new tools and Spotlight shortcut, this update also includes several quality-of-life improvements and bug fixes:
