Tarbat,
As I said, it's not something that I'm really going to get excited about one way or the other. I can see the advantage of having a full screen radar display on one monitor and the full width aircraft list on the other. It's OK with my big monitor running at 1280 x 1024 and it's OK on my wide-screen laptop, but it can be a bit crowded on my smaller monitor 1024 x 768.
As it is, I can't see all the columns I want to see in the list whilst keeping the map a reasonable size. I usually have the "ADS-B Only MyFlights button hidden by the map - I bet there are some people who don't even know this button exists :-)
Whilst I rarely use the Esc - full screen view (just selected it now), it does give a very good (and impressive to visitors when giving a demo) display and if I could have the list visible on my other screen, then I would. My 2 screens are a different size as noted above, so I can't really drag the RB window to cover both.
Is it raining up there in the frozen north? It's pouring down here in the Midlands - never mind, it's the indoor RC flying day tomorrow at my local club, just right for the summer!
All the best
