[Feature] Sidebery-like features and split-screen

[Marin-Kitagawa]

Description

Sidebery has a lot of features. But there is no equivalent to Sidebery in Chrome. Below is the image of my Sidebery setup.

The left most icons denote the panels similar to Workspaces in Edge, Vivaldi, Arc, Opera and Floorp. The Sidebery sidebar completely hides similar to Arc browser (my customization).

I'd like the following features to be brought into Brave

1. Workspaces
2. Nested Groups/Nested Folders similar to Arc & Sidebery
3. Manual and Automatic hibernation (unloading) of tabs, groups and Workspaces
4. Containers (as in Firefox)
5. Tab title customization
6. Clearing cookies per site
7. Split-screen view
8. Native mouse gestures

Basically, all Sidebery features, Containers in Firefox and Split-screen view (split screen is supported by Arc, Vivaldi, Edge, Floorp) and mouse gestures (which are natively supported by Edge, Vivaldi, Opera)
