Hello priyam.basu,
1) Unfortunately, it is not possible to position a window’s header and content side by side horizontally.
2) When you export the layout, the information is stored as a JSON string. Here is how the docking from the Default Functionality demo is exported:
"{"panel0": {"window1":{"collapsed":false},"window2":{"collapsed":false}},"panel1": {"window3":{"collapsed":false},"window4":{"collapsed":false}},"floating":{},"orientation": "horizontal"}"
This is all the information that is exported and it is sufficient for importing the layout when needed.
Best Regards,
