Left Navigation

Add basic navigation functionality to the left side of the screen.

At the top of the browser page is the tab bar, at the bottom is the operating system's status bar, on the right side is the scrollbar, leaving only the left side without any pre-set functions. Left Navigation adds a page/tab navigation area on the left side of the screen, allowing for easy management of page/tab with just one hand using the mouse. The specific functions are as follows: Clicking with the left button on the upper half: navigates back to the previous page. Clicking with the right button on the upper half: moves forward to the next page. Clicking with the left button on the lower half: closes the current tab. Clicking with the right button on the lower half: restores the last closed tab.
