Greetings. First part of the question is: is there any new firmware planned for P4ProV2 or GL300K remote (app update etc)?
Second part is: is there any way that you might consider unlocking the integrated screen for 3rd party apps, or at least provide a way to connect external devices to back usb port? Buying a second remote just to be able to run apps for mapping etc seems unreasonable.

I would agree there should be some freedom with Items that are not being supported. So perhaps the final firmware allows the release of the locked down OS.
