Make 2017 TV sets that have latest USB ports, at least 3.0 so it is possible to find a compatible USB HDD WebOS will work properly with.
Install sufficient memory to run WebOS Apps without constant restarts or inform customers apps may not work properly.
Put a clearly accessible filer by Genre choice from the main program guide (something Toshiba TV and others have had for many years on their EPG's). Going out of the main EPG into the limited snapshot guide then finding the sort by Genre option is clunky. A zoom function on the main EPG to show more than just a couple of hours ahead would be ideal as well. Even my £70 supermarket own brand TV can manage these simple functions so come on LG match up.
