Sessions View is used to manage sessions and runtimes in the workspace. The view consists of two tabs: Sessions and Runtimes.
Sessions tab contains all definitions of sessions from workspace, and allows to add, remove and edit them. This tab is also used for running and debugging sessions.
Similarly, Runtimes tab is used for managing all runtimes from the workspace.
By default Sessions View is visible in Magik Development Perspective. To add the view to the current perspective, click Window > Show View > Other... > Magik > Sessions.
