какое нахер изи..



I've been trying to replicate the Yandex Browser's tab management feature in Firefox, where you have separate "windows" or panels of tabs that you can quickly switch between. In Yandex, this works like distinct workspaces: each panel holds its own set of tabs, and switching hides the others, making it easy to organize and navigate multiple projects without cluttering the main tab bar.

What I want:

Multiple independent panels (or sidebars/workspaces) for bookmarks and tabs.

Ability to switch between these panels seamlessly (e.g., via hotkeys, sidebar tree, or dropdown).

Each panel acts like a separate "window" within the browser: tabs in inactive panels are hidden/unloaded to save memory.
