Cultured Code's task management app Things has been updated to support the new iPhone Duo device. The update introduces an adaptive layout that adjusts to the iPhone Duo's various configurations. This includes how the app looks when the device is closed, fully open, or partially folded. The interface also supports both portrait and landscape orientations. Upon opening the iPhone Duo, users will find a new sidebar for list navigation, a first for the iPhone version of Things. Additionally, the app now allows for multi-window support, enabling users to open two Things windows side-by-side. Tasks can be organized by dragging and dropping items between these windows. Controls are positioned in a vertical bar for easy thumb access, including the Magic Plus button for adding new to-dos. When a keyboard is connected, users can leverage the app's full keyboard features. These include persistent selection, shortcuts, and Type Travel for efficient navigation. The updated Things 3.25 is available for download now.
