OneMore is a OneNote add-in that extends the desktop application with keyboard-driven commands and content management features.
OneNote's native interface lacks keyboard shortcuts for many common tasks and offers limited formatting consistency across notebooks. OneMore addresses this by providing a command palette with over 200 commands accessible without leaving the keyboard, custom text styles and table themes for consistent formatting, and tools for managing content like auto-generated tables of contents that stay synchronized with edits. The add-in also handles markdown pasting, syntax-highlighted code insertion, image manipulation, diagram rendering, and snippet management—all integrated directly into OneNote's interface.
Developers and power users who spend significant time in OneNote and prefer keyboard navigation will find the most value here. The tool suits anyone managing multiple notebooks who wants consistent styling, quick access to formatting commands, or the ability to save and reuse content blocks. The add-in is free and open source with no subscription or required telemetry, making it a low-friction addition to an existing OneNote workflow.
Development activity shows consistent engagement with community contributions welcomed through documented setup instructions. The project maintains an active release cadence with downloadable binaries readily available. Documentation is comprehensive, with a dedicated guide covering all features and commands in detail. The codebase is written in C# and uses LINQ-to-XML for document manipulation, reflecting a mature approach to OneNote's XML-based storage format.
