Features

Umo Editor Mobile is a document editor designed independently for touch-first scenarios, rather than a simple trimmed-down version of the desktop UI.

It organizes its capabilities around the core mobile workflow of “preview, edit, save, and leave”, while keeping configuration semantics, method naming, and the extension system as aligned with Umo Editor and Umo Editor Next as possible.

Key Differences from Desktop

Different interaction structure Different on Mobile: mobile is centered around the navigation bar, bottom TabBar, bottom toolbar, and popup panels, rather than the desktop top toolbar and complex side areas.
Different capability focus Different on Mobile: mobile prioritizes reading, lightweight editing, saving, and leave flows, while desktop focuses more on complex productivity.
Different capability boundaries Partially Unsupported: printing, fullscreen, AI Chat, some tool panels, and some desktop events/methods are not yet exposed on mobile. More details are described in the Roadmap.
Different default view priority Different on Mobile: mobile defaults to web layout instead of page layout.
More app-like entry points for outline, search, and the more panel, all managed by internal component state. Mobile-Only
