The features of the sub-launcher "Smart Sidebar" provided by OPPO are:
-Can be called from anywhere
-System tools such as screenshots and screen recording can be used
-Open apps in multitasking (floating window or split screen)
-Save images and other data, open them, and share them
It acts like a clipboard.
It is not available by default, so enable it and learn how to use it.
[Settings] ⇒ [Special features] ⇒ [Smart Sidebar] ⇒ When you enable the "Smart Sidebar" toggle, a faint vertical floating bar will appear slightly to the upper right of the screen (default state).
Swipe this bar inward to open the "Smart Sidebar".
The system tools that can be operated from the Smart Sidebar are
"Screenshot", "Partial screenshot", "Screen translation", "Recorder", "Quick memo", "Calculator", "Screen recording", and "Screen lock".
When you tap an app icon, if it supports the "floating window" function, it will automatically open in a "floating window".
If not, it will open in full screen.
Long press an app icon and drag and drop it to split screen.
If the app does not support split screen, the message "Split view not supported" will be displayed when you long press it.
If the currently open app does not support split screen, the message "Drop not possible" will be displayed when you drop it.
If you enable "Show recent files" and "File Dock",
the folders "Recent files" and "File Dock" will be created in the Smart Sidebar.
In "Recent files", you can view images, videos, and documents from the past 30 days and "share" them.
In "File Dock", you can view files that you intentionally saved, open homepages from URLs, and reuse text.
You can also "share" them like "recent files".
To save files to "File Dock", select "Smart Sidebar File Dock" in "Share".
