Apart from the pop-up URL menu not applying dark mode based on the theme, everything else is great! Moreover, with the new sidebar design, the user experience is close to that of a browser that supports window splitting!

Really like this addon. Please take a look at what zen-browser is doing with splits for further inspiration.

Thanks!

Thank you, this is the feature I wanted.
However, like Yandex Browser, Whale Browser, Edge Browser, and Vivaldi Browser, closing and opening the window does not keep the content displayed.
