It may be specific to my environment. I'm using Windows 10, 1920x1080 at the recommended 150% scaling. Just tried 3200x1920 at the recommended 250% scaling, logged out/in and it's exactly the same...which is actually a nice improvement because 7.1 had scaling issues.
This is how it always opens. The first time I used it, I went a little crazy trying to figure out how to add an operation. Maybe take the same approach you do with panel operations, which have buttons on the side. That would be more consistent too.
Notice the cutoff option at the bottom.
