I use the spectrum display quite a lot (coming from that sort of RF background) probably more than the waterfall.
Ideally I'd like to be able to just display the spectrum display, or be able to swap the spectrum display and waterfall positions and sizes around and turn one or the other off.
I know this has been discussed previously and there are various problems associated with how it could be implemented.
But I was looking at the GUI earlier today, and turned off the band bar, so that I only had the spectrum display and waterfall visible, and it struck me that maybe the size of the spectrum display could be increased when the band bar is switched off, as the waterfall doesn't really benefit from the increased display space, and can already be scrolled if required.
Not a biggie, but a nice to have, if at all possible.
