## Summary
The KDE community has released Koko, an image gallery application designed to function across traditional Linux desktops and touchscreen devices. The software provides thumbnail-based browsing, folder navigation, date-based organization, and basic editing tools including crop and resize, with confirmation dialogs to prevent accidental edit loss. Koko is built with an adaptive interface that responds to different screen sizes and input methods, placing it within KDE's convergent application strategy that targets both Plasma Desktop and Plasma Mobile deployments.

The application is implemented in C++ and licensed under the GNU Lesser General Public License v2.1 or v3.0. Source code and development activity are hosted on KDE's GitLab instance at invent.kde.org. Koko enters a crowded field of open-source image viewers on Linux, competing with established alternatives including KDE's own Gwenview, GTK-based Loupe, and hardware-accelerated options like Oculante and PhotoQT.

## Convergent design and feature set
- **Adaptive interface architecture:** Koko implements KDE's convergent application pattern, using responsive design principles to adapt layouts and input handling across mouse/keyboard desktop environments and touchscreen mobile interfaces.
- **Image format support:** The application renders SVG files in addition to standard raster photograph formats, expanding utility for users working with vector graphics alongside camera images.
- **Organization models:** Beyond folder-based navigation, Koko groups photographs chronologically with date-based collections, providing an alternative browsing paradigm for large unsorted image libraries.
- **Editing safeguards:** The software includes confirmation prompts before discarding image edits, a protective measure against accidental data loss during basic crop and resize operations.
- **Multi-modal input:** Interface elements are designed for simultaneous compatibility with mouse, keyboard, and touchscreen interaction methods without requiring separate builds or interface modes.

## Why it matters
Koko strengthens KDE's position in the mobile Linux space by adding a polished gallery application to Plasma Mobile's application catalog, addressing a gap that has historically favored GTK-based alternatives on distributions like Phosh and Lomiri. For distribution packagers and downstream projects like postmarketOS and Manjaro ARM, the availability of a convergent KDE-native image viewer reduces fragmentation in the application stack and provides users with consistent behavior across desktop and mobile deployments.
