知乎安卓平板端优化 is a free add-on and tool designed specifically for Yandex browser on Android tablets. It aims to enhance the user experience of accessing Zhihu, a popular Chinese Q&A platform, on a horizontal screen.

Using this add-on, Zhihu's main pages are automatically forced to load the PC version, eliminating the need for manual selection of the browser's PC mode. Additionally, the add-on optimizes touchscreen operations by rearranging the top bar to the left side, reducing screen occupation, and restricting page width to prevent horizontal scrolling.

This add-on is primarily effective on Zhihu's homepage, answer pages, personal profile, search page, topic page, and column page. Other pages do not require optimization.

Please note that this add-on is specifically designed for horizontal screen usage on Android tablets and is only compatible with Yandex browser, as it is the only Android browser that supports Google extensions. It is recommended to use the official Zhihu app in portrait mode for the best experience.
