We're actually planning on that exact thing - disabling the buttons during loading (and mode switches). It should help avoid the issue :)

On the preview window: currently it has a 'soft' block to prevent people accidentally leaving the edit page. We're planning on putting in a warning instead. On collapsible tables and tabber - it can be difficult to get the custom JS to run in the 'right frame', but it's something we're looking at.
