The real issue here is that Ralph is trying to cram too much functionality into each tab. As a result, some things are simply not intuitive. Proper segregation of the UI components by function would go a long way to making it much more usable.
And don’t get me started on the use of fixed-width fonts (I know 3.5 is going to eliminate this), non-standard round dials, etc. The entire GUI screams non-standard no matter which window manager you use (Windows or Mac).
Etc.
