Hello
With the Mooney M20TN Acclaim, when I click on the "View" button at the bottom of the MFD to change the visualization of the flight plan data, the second-to-last button on the right does not display the "Back" label, there is instead your custom "Checklist" button. To be able to quit the "View" mode, I have to press the 3rd button without label at the bottom of the MFD to make the "Back" button appear instead of your "Checklist" button and so quit the "View" mode of the flight plan.
I haven't tested, but I think there's the same problem with the M20r Ovation III.
