I think Multi Commander would be more popular if you change some of the defaults to make it look better out of the box.
The main change is to have extra row height in list view. I set mine to 5. I think it should be 5 by default, or at least 4. I also think the border around the active panel should be black.
I know Multi Commander is extremely customizable, but most people do not want to go searching to figure out how to customize it.
