The libraries are available so that users can organise their components into several groups, making it easier to manage when building a system. To create and manage your libraries, go to the Library Browser located on the left navbar. You can filter your view by public or private ones.
The button highlighted in the previous image allows you to dive into a library and view its current components. There, you can create new libraries by clicking the New Library button and remove them by clicking on the red cross next to an item.
You can add components to your libraries by clicking the '+' button. Furthermore, you can delete libraries by clicking on the trash-bin icon.
When adding new components, a modal will be show listing all the available ones. Just click on the component's '+' icon in order to add it to the library.
Libraries can be made public to share them with everyone. To do this, simply click on the switch to set the current status.
In a public library just the public components will be shown. If you include any of your private components, you will be the only one seeing them.
