What is new in DockLens 1.0.12
**What's new** - **Redesigned Settings.** The Settings window now uses a sidebar like macOS System Settings: General (app info and updates), Appearance, Behavior, Recently closed and Permissions. - Permission rows show their status at a glance: green when granted, orange when not. - No settings were added or removed, and your existing settings are kept. Updating from 1.0.4 or later keeps your permissions — just click **Open Anyway** once for the new version. Requires macOS 26 or later. Install steps are in the [README](https://github.com/firstfu/DockLens-app#install). --- **更新內容** - **設定頁改版。** 設定視窗改成 macOS「系統設定」式的側邊欄:一般(App 資訊與更新)、外觀、行為、最近關閉、權限。 - 權限列一眼就能看出狀態:已授權為綠色、未授權為橘色。 - 沒有新增或移除任何設定,原本的設定都會保留。 從 1.0.4 以後的版本更新會保留權限,新版只需要再按一次「強制打開」。 需要 macOS 26 以上。安裝步驟見 [README](https://github.com/firstfu/DockLens-app#install)。 SHA-256: `5430af626370ac56b8872aec965c4db7b80b03016e98d6c80d113f1b9a0595f2`
