Grimoire is a simple markdown editor I built using React.js and Electron, along with other technologies, it has full support for the Markdown syntax and is available on Windows, Linux and MacOS.
App home screen, this is the notebook view which allows the user to organize documents into collections and preview/edit those same documents in the same place.
This is the dedicated document editor window, this is the window that pops up when you click to edit a particular document on the initial screen.
