My File Bookmarks extension for Visual Studio Code enables bookmarking of entire files and folders, with the aim of making large projects easier to navigate. The extension creates a new 'Bookmarks' sub-view within the Explorer tab, as well as contributing commands and context menus. I was inspired to create this extension while working on a work project with a large, deeply nested file structure, in which I often found myself wanting an easy way to bookmark files without going as far as pinning them to the tab bar.
The extension is available on the Visual Studio Code Marketplace. You can find it by searching for File Bookmarks, or by following this link.
The extension is built in typescript using the Visual Studio Code Extensions API.
