The Global Drawer is a standard element in KDE mobile applications. It contains an application's main menu, and any functions which are not part of the application's main usecases but are not specific to the current context either.
Use a Global Drawer whenever your application has any functions which are not central enough to the application's main purpose to put them in the main user interface, and which are not dependent on the current context. For context-specific actions (e.g. those affecting a selected item), use the Context Drawer
The Global Drawer is opened by swiping in from the left or right edge of the screen (depending on a system-wide setting) and closed by swiping in the other direction or tapping outside of it.
A Global Drawer may contain the following controls:
The main menu
Do not use the Menu Drawer for navigation purposes.
