I really like the two screen mode, really helps with multiple monitors. But there’s one gotcha. Focussing one window doesn’t bring its companion window to the top, which is problematic.
The best example: I’m working with two instances of EDT. Let’s say I’m viewing the first on my main monitor, with its companion window on the secondary monitor. If I switch to the second instance, the second monitor continues to display the first.
Focussing any window should bring all windows from that process to the top.
