# Overview Karedi's UI is build from individual components with [*main editor*](https://karedi.gitbook.io/karedi/user-interface/middle-components/main-editor) being the most important one. Some components are organized into groups of tabs e.g. "Tracks" and "Audio" are in the same group. Only one of the tabs from a given group can be active at the same time. This is the default view:

And with tab groups switched to the hidden tabs (just click on a tab caption to show it):

Dragging tabs from one group to another is not supported. You can however resize the components freely:

## Dark mode By default Karedi is opened in the light mode. There is also a dark mode available:

You can switch to the dark mode by: 1. Going to the menu *View* -> *Switch mode* 2. Clicking moon (if you are in light mode) or sun (if you are in dark mode) icon in the [*toolbar*](https://karedi.gitbook.io/karedi/user-interface/toolbar)

Last used mode is remembered and will be applied on application start up.
