DSH Desktop Widget Center: Native macOS Mini Windows and Multi-Instance Management

DSH Desktop Widget Center is a native macOS plugin that allows users, when running local agents, to access real-time desktop information—such as stock quotes and sticky notes—via a standalone mini window, avoiding a fragmented web experience. Developed by NattoCB, the plugin supports multi-instance management and uses NSPanel + WKWebView to implement borderless windows with draggable and persistent positioning. It integrates the market_quote tool, enabling stock prices to be queried directly within conversations. Installation requires Xcode Command Line Tools, and it supports multiple data API sources, including Tencent and East Money, as well as adding new types through Type Studio.
