Up / Down arrows are already defined. They adjust the position of the subtitles. Left / Right adjust the delay of subtitles.
Not entirely true. Yes up/down-arrows are defined as many things. Navigation for one. The adjusting subtitles only work if you go to option -> adjust subtitles.
I’m talking about when a moviefile is playing - simply pressing up/down would adjust volume. Up/down-arrows does nothing as it is now, so it would be a simple feature to add in new FW. The ability is already there - it works if you use a connected keyboard - it just hasn’t been asigned to any buttons on the remote.
Why? Would you ask - is this a good feature? Because a lot of people have a secondary sound system setup and need a second remote to adjust volume. Being able to adjust volume directly from the HUB remote would mean that a single remote would be enough…
