I second this. I've just learned about the System>Compare paradigm, and meh.
So my current solution, since I just MUST see the little platform guy next to my platform events, was to hack the platform behavior's javascript files to add my own custom comparison conditions.
The good news: this took about a minute.
The bad news: I'll have to re-patch it every. single. update. and it will make sharing .capx impossible.
