What is todoist-hidesidebar?

Todoist Hide Sidebar is a small browser extension that adds a toggle button to Todoist, the popular to-do list app. With it, you can collapse the sidebar that lists your projects and labels, giving your task list more room to breathe. When you want to navigate between projects again, you click the button to bring the sidebar back. The extension is written in JavaScript and works by injecting a bit of code into the Todoist web interface. That code adds a new button to the page and wires it up to show or hide the sidebar element when clicked. It is a lightweight, focused tool that does one thing rather than trying to overhaul the whole Todoist experience. The people who would find this useful are Todoist users who spend a lot of time in the web app and feel cramped by the always-visible sidebar. If you are working on a smaller laptop screen or just prefer a clean, distraction-free view of your tasks, this extension gives you control over your screen real estate without having to dig into Todoist's native settings. The README itself is marked as under construction and consists mainly of before-and-after screenshots showing the sidebar visible and then hidden. There is not much else in the way of setup instructions or feature documentation, so you would need to look at the code or install it directly to understand exactly how it works in practice.
