File icons: vscode-icons - first file icons for VSCode (AFAIK) and they are still best looking (IMHO).
Code alignment: Alignment - if you need to align those assignment rows (:=, = etc.) to look prettier
Bookmarking code: Bookmarks - you know what to do with it, right? :)
EditorConfig: If you need to force codestyle in your team
Guidelines: Guides - draws guiding lines between brackets
Markdown: Markdownlint, Markdown PDF
Syncing VSCode config: Shan Khan's Settings sync (already mentioned earlier by somebody else)
ToDo: TODO Highlight (searches code for TODO: FIXME: etc., highlights them in code as well as lists them)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
