CSST 1.0.0

Custom Search System Tabs (CSST) is a Tampermonkey userscript that lets you customize the navigation tab bar on Google, Yandex, Bing, and DuckDuckGo. You can hide tabs you don't use, rename them, redirect them to any other service (e.g. make the Videos tab open YouTube), and add your own custom buttons to the search bar. All changes apply live, without page reload. Supports 10 UI languages and dark theme auto-detection.
