One thing I really miss from my Directv Genie is a feature called “Doubleplay”.
What this does is allows you to pause one channel (for example, during a commercial break), then click the down arrow (on the directv remote) to watch the previous channel you were watching (or select a new channel to watch). So, the last channel viewed prior to the current one would appear, leaving the previous channel paused.
Once you finish watching the 2nd channel, click the down arrow again to return to the previous channel (still paused, but auto resumes from the point you left off). You can then FF through the commercials and resume watching the program.
For Channels, while watching a program the “swipe up” feature is unused, so perhaps that could be used for doubleplay function.
