Tracks commands, directories, and hostnames to enable click-to-download files, drag-and-drop uploads, and command history per host, enhancing workflow efficiency.
Includes an LLM chat window that can interact with terminal contents for context-aware help, command execution, or output explanations, adding intelligent support directly in the terminal.
Sessions run in long-lived server processes that survive app crashes or upgrades, reconnecting exactly where you left off, ensuring minimal disruption.
Offers a full Python API for automation and customization, allowing users to create status bar components, triggers, or entirely new features, as highlighted in the README.
Limited to macOS only, making it inaccessible for developers on Linux or Windows who need a unified terminal solution across platforms.
Building from source requires interactive prompts for dependencies like Xcode and Homebrew, as per the README, which can be cumbersome for casual users or those unfamiliar with the toolchain.
The vast array of advanced features, such as AI chat and inline images, might overwhelm users who only need basic terminal functionality, leading to unnecessary complexity.
Nightly builds are explicitly noted as less stable than official releases, which could introduce bugs or instability for users seeking the latest features.
