According to one general aspect, a computing device may include an application configured to create a tab in a context of a window, and a window manager configured to register the tab with a first UI element registry. The window manager may be configured to receive, over a network, at least a portion of a second UI element registry from a secondary window manager of a secondary computing device. The portion of the second UI element registry may identify a remote tab previously registered with the secondary window manager. The window manager may be configured to cause a display to provide a graphical arrangement of the tab and the remote tab.
