Thanks.
This is not great either though, since you can't close the code window, that just closes the whole ide session, so you can't make it fully focused on the serial output.
I've also found that the library manager and boards manager jam themselves in at the left, meaning that you have to resize windows to see the content. The older IDE was far better with windows, rather than this constant having to trade one piece of screen real estate for a different function all the time.
I'm not loving the new IDE so far
