Method and system of providing for cross-device operations between user devices

A system of providing for cross-device operations between user devices, the system comprising an intermediate device connected to the user devices and comprising one or more processors with access to at least one memory, which, alone or in combination, are configured to provide for execution of the following steps:

• maintaining state information on different elements in different sub-views displayed respectively on first and second ones of the user devices, the first and second user devices being different from each other;
• and
• performing at least one of:
• migrating and synchronizing the state of one of the elements which is moved from the sub-view of the first user device to the sub-view of the second user device, or
• generating a shadow element on the sub-view of the second user device and linking the shadow element to one of the elements on the first user device which is duplicated from the sub-view of the first user device on the sub-view of the second user device, and updating the states of the linked elements.
