Butterfly 2.4.1

"Butterfly" by Linwood is an innovative and versatile terminal-based application designed to enhance the user experience for developers and system administrators. This open-source project stands out for its seamless integration of web technologies, providing a modern twist to traditional terminal usage.

At its core, Butterfly is a web-based terminal emulator that allows users to access their terminal sessions through a web browser. This feature is particularly beneficial for those who need to manage multiple remote servers or workstations, as it offers the flexibility to connect from any device with internet access. The web-based interface is intuitive and responsive, ensuring a smooth user experience even on mobile devices.

One of the standout features of Butterfly is its support for multiple simultaneous sessions. Users can easily switch between different terminal sessions within the same browser window, streamlining workflows and improving productivity. Additionally, Butterfly supports split views, enabling users to view and interact with multiple terminal sessions side by side.

Security is a top priority for Butterfly. The application includes robust authentication mechanisms to ensure that only authorized users can access terminal sessions. Furthermore, all data transmitted between the client and server is encrypted, providing an additional layer of security for sensitive operations.

Customization is another area where Butterfly excels. Users can personalize their terminal experience with a variety of themes and settings. Whether you prefer a dark mode for late-night coding sessions or a specific color scheme to match your workflow, Butterfly offers the flexibility to tailor the interface to your preferences.

Performance is a critical aspect of any terminal emulator, and Butterfly does not disappoint. The application is optimized for speed and efficiency, providing a lag-free experience even when handling complex commands and large outputs. This makes it an excellent choice for both casual users and power users who demand high performance from their tools.

Butterfly also boasts a range of advanced features that cater to experienced users. These include support for custom keyboard shortcuts, clipboard integration, and the ability to run scripts directly from the terminal. These features, combined with the application's overall ease of use, make Butterfly a powerful tool for anyone who relies on terminal access for their daily tasks.

In summary, Butterfly by Linwood is a cutting-edge terminal emulator that brings the power and flexibility of web technologies to the traditional terminal experience. Its combination of a user-friendly interface, robust security features, and extensive customization options make it a standout choice for developers and system administrators alike. Whether you're managing remote servers, developing software, or simply need a reliable terminal emulator, Butterfly is a tool that deserves serious consideration.

Release notes:

New Release
Delayed autosave:
Delayed auto save means Butterfly waits 1–10 seconds (2 seconds by default) after your last change before saving, so devices with slow hardware can still enjoy auto saving without constant churn. Not only that, the saving process has been improved under the hood by running it in the background so you can draw without the app freezing. Additionally you can now see the current save state as a tooltip on the save icon. Issues around save ordering and state updates during autosave are also fixed.
Thumbnail capture improvements:
You get better thumbnails: the app now captures the correct center of the viewport and a preview will be shown of your capture.
Template import and export improvements:
There are fixes for importing and exporting templates. You can export templates to the tbfly format and selectively choose which templates to export. Imports are more reliable, including when no document is open, and tbfly imports now work as expected. Absolute read-only file handling on save was also corrected.
In this part, another bug affecting backgrounds with lines has been fixed—now they render the last row and column even when only partially visible.
Improved PDF handling:
PDF handling is more efficient. The underlying PDF library was replaced, and the app no longer crashes in this area. The PDF import dialog has clearer defaults and descriptions, and overall reliability around PDF-related flows has been improved as part of broader stability work.
Drawing improvements:
Element creation now feels smoother when you release the pen. We fixed flickering and eraser artifacts, including a bug where the eraser could produce duplicate IDs. Background lines render the last row and column even when they are only partially visible. We also corrected scaling behavior for multiple elements and for pen elements.
File view and UI improvements:
The grid view now has better spacing, and filenames wrap more gracefully on desktop. Theme names display correctly, including
