单标签页限制：确保每个笔记、Canvas（白板）或其他文件在整个工作区中仅占用一个标签页，避免重复打开相同的文件。
智能重定向：无论您是通过文件树、快速切换（Quick Switcher）、全局搜索，还是通过双链点击打开笔记，若该文件已打开，插件会自动聚焦到已有标签页，无需手动寻找。
视觉无缝过渡：优化了标签页拦截逻辑，瞬间自动关闭新产生的空白多余标签页，减少页面切换时的视觉闪烁与白屏抖动。
全文件类型支持：不仅支持标准 Markdown 笔记，还完美兼容 Canvas、数据库以及其他第三方插件生成的自定义视图文件。

待插件上架后，可在 Obsidian 内直接安装：

启用插件后即可自动生效，无需进行繁琐的额外配置。
当您尝试以任何方式（点击链接、搜索结果或文件树）打开一个已经在其他标签页中激活的笔记时，插件会自动将您的视线和焦点切换到原本已存在的那个标签页上，并温和地关闭新生成的空白页面。

English

A lightweight Obsidian plugin that prevents opening duplicate tabs for the same note, keeping your workspace clean and tidy.

Single Tab Constraint: Ensures that each note, Canvas, or other files can only occupy one open tab in your active workspace, preventing clutter.
Smart Redirection: Whether opening a note from the file explorer, Quick Switcher, global search, or internal links, the plugin automatically shifts focus to the already-open tab.
Visual Glitch Reduction: Optimized tab interception logic that instantly closes newly spawned empty placeholder tabs, minimizing visual flickering or brief white screen flashes.
Universal File Support: Works smoothly with standard Markdown notes, Canvas, database files, and other custom view types generated by third-party plugins.

Once this plugin is approved, you can install it directly from Obsidian:

Download the latest release (main.js, manifest.json, styles.css) from the Releases page.
Create a folder named unique-tab under your vault's plugin directory: <vault>/.obsidian/plugins/unique-tab/.
Copy the downloaded files into that folder.
Go to Obsidian Settings > Community plugins and enable the plugin.

Once enabled, the plugin works automatically in the background without requiring any manual setup.
When you attempt to open an already-opened note (via search, explorer, or links), the plugin will instantly navigate your view to the existing tab and quietly dispose of the newly created duplicate.
