Feature Request: Modal Editing Plugin (Doom Emacs) for SiYuan

Hi @88250 and @Vanessa,

I feel like SiYuan's block-based editor can be crazy efficient with some keyboard-driven workflows. I'm not 100% certain but I feel like the true power users might want:

• Normal/Insert/Visual modes
• Vim-style motions (hjkl), operators (d, c, y) and text objects
• Block-aware commands
• Customizable keybindings via settings

Are we able to consider a standalone TypeScript plugin using SiYuan's existing API to override keymaps and manipulate blocks (like per subject, integrate Doom Emacs for example would be amazing).

Roll out in phases: basic modes → text objects/operators → macros/marks → mobile adaptations.

Benefits:

• No impact to the core editing capabilities; optional install for advanced users
• Low maintenance via plugin API
• Attracts large Vim/Emacs users (a more modern VIM & Emacs) and showcases SiYuan's extensibility to other applications beyond just note taking

Please consider adding a modal-editing plugin to the roadmap, to empower keyboard-centric workflows.
