"Select All" "Select none" button in channel mapping

[Deusxmachina]

Or just the ability to highlight more than one channel at a time. Or maybe it already can do it somehow. This would be for both the channel mapper and for the first tuner screen with the channels.

I've accumulated a ton of extra channels from different EPGs or something, and that's just from OTA. Today I was messing with using a cable EPG for OTA and had to uncheckmark seemingly 500 channels I'm not using. It took literally 10 or 15 minutes of button pressing. Not the worst thing in the world, but a wish.

Sub did say a while back one of the things he was gonna work on was the channel config screen. But he is a busy man so not sure where it is on his list of priorities
