While it doesn’t bring it up to current standards, it does have a tabbed UI that you can enable by going to View --> User Interface

Personally, I don’t fully understand why they don’t make that the default and keep supporting the toolbar design as they’ve always done. I can’t imagine there would be a big backlash from existing users who prefer the toolbar UI

MSFM 2000 was the one (and only one) that I’ve played, and unfortunately no, it just pauses the game right on impact.
