モナコノート

This is a notepad that includes Monaco Editor, which is familiar as the text input area in VSCode. It comes with markdown preview by default, but that's just a bonus feature.

It supports a vertical tab bar, tab save functionality, snippet registration, selectable fonts for both the editor and preview sections, Japanese/English language switching, dark mode/light mode switching, and syntax highlighting in the editor section.

Of course, it also supports saving and loading files. It's built using Rust and Tauri. (The build process was tough...)

*Additionally, it also supports UTF-8 and Shift-JIS character encodings. While there's a setting for this, newly created tabs will use the character encoding specified in the settings.
