Steam Little Toolkit от Alejandro Akbal

This extension mostly introduces nice additions like:
· Hiding the games that you already own, so you only see new games,
· Actually hiding the games that you ignore, not putting a badge and graying it out
· Removes the pesky autoplaying livestreams :)
· Bypasses automatically the annoying Age check and the external Url check

All the settings are optional and can be toggled via the menu!

Check all the features and future updates on the GitHub below

You can check the source code, planned updates, alert me of some bugs or just say what you want added on the extension's GitHub!

If you're worried about security: dont worry anymore cause the extension doesnt load on secure pages like the cart, checkout, login or register page.
