I would like to be able to download software updates while still being able to use the device to watch other items. As of 1.0.24, if you leave the software update screen, download will continue for some random amount, maybe 9-15%, then silently stop downloading. You have to go back into the software update screen to re-check and restart the download.
On my rural wireless connection the download can take a very long time. Best case scenario would be to be able to tell the PPMax to start the download, be able to go back to DLNA steaming or app, and PPMax would prioritize current video streaming packets, and download in the background as it can, and automatically re-start a failed firmware download in the background.
