Choose your layout
Classic opens first unless you save another default. Use Try the new layout or View old layout to switch. A layout in the page address takes priority for that visit. If saving a default fails, your previous choice remains; try saving again. Switching keeps the same page and its current choices.
Keep the original controls
The same account choices, balance, statistics, history and message controls remain. Switching layouts does not send a message or change an account. Existing service reads keep their original behavior. Existing loading and error behavior remains.
