To use your favorite functions quickly with one tap without the need to go to the main menu, put their buttons to the function panels. There are some already by default but it is possible to customize their position, number, and features they turn on.

How to open the panel settings:

• long-press any of the buttons in the bottom or right panel and select Modify panel from the popup
  
• OR go to Menu > Settings > Controlling > Panels&Buttons > Set functions panels

• tap “+“
• Add function button - opens the list of features to select
• Add link to app - opens a list of apps for which you can add a shortcut (since Android 11, not all apps can be added)

• you can drag the buttons by their icons between the bottom and right panels (the maximum number in the bottom panel is 6). The sign in the upper right corner of all items indicates the position in the bottom or right panel.
• automatic button placing - use this if you have a tablet or a bigger screen, or you rotate the screen often. It connects the two panels into a flexible one:
  
• to change a button function or remove a selected button, tap next to the button name and select from the popup.

Both the bottom and right panels can be hidden automatically. This can be set in Menu > Settings > Controlling > Panels&Buttons
