I've tried many similar extensions to highlight TODO and FIXME comments, but all were either doing too much or too little, and hard to configure. That's why I created my own.

Here are the main features of the extension:

• Very minimal and fast
• Useful defaults to cover most use cases
• Supports Bash, CSS, Elixir, Erlang, HTML, JavaScript, Lua, Markdown, Perl, PHP, Python, R, Ruby, SQL, TypeScript, and any other language with C-style comments (// or /* */)
• Doesn't add distracting highlights to the scrollbar
• Supports light and dark modes out of the box, and doesn’t come with insanely bright colors by default

Try it now in VS Code!
