You can't changes the listed apps in the shortcut button. Though to be honest I never use it, I use the apps directly on my tv as they work better and are more stable.
The tiles are meant to make it easier to find what you are looking for, by having a picture, as the box is fairly responsive it doesn't take too long to find and on the recordings screen they are listed with most recent recordings at the top. On the left you can filter a couple genres like movies. You can also list by recently watched.
As the mini boxes are just slaves, the recordings and downloads all happen on the main box and stream to the mini when playing. I can easily spot what my wife or daughter have chosen to watch as I have no interest in those and easy to tell what they are called. I never even look at those and don't go in to delete.
The Q menu style was all about the tiles and making the menus easier to navigate, I did take me a week or so to adjust to it, but now it's so easy to get to where I want.
Searching isn't something I do often but the voice search is probably the fastest way to find things. Press and hold, say a programme name or actor name and it finds everything it can. You can also search by quoting a movie, for example "who ya gonna call" brings up ghostbusters.
Yes it's slower as on the 2.4ghz WiFi but an ethernet makes it quicker and I usually click to download and you get a message on screen telling to its ready to watch within a minute usually. Sometimes less.
Yeah, I don't imagine my parents will use many apps either to be fair, they'll just want to watch TV.
I can't see my parents using the filters, I'm not sure I'd be bothered either, everything on the box is so clunky it probably wastes more time than it saves. I don't remember the last time I recorded something and saw the name of it in a list (e.g. The Walking Dead) and thought, "I don't know what this is, if only there was a generic picture from the show to help me identify if this is the episode of The Walking Dead". I just wish there were options to disable it so it could be a little more like the old style boxes. Give the user a bit of choice.
I'm also annoyed that the mini boxes don't have their own storage for recordings as that could solve the issue of identifying recordings. While I'm unlikely to delete the wrong recording, I can't speak for my parents. Being able to filter the recordings by the box that initiated them would speed things up, my dad is likely to record the vast majority and use the main box, so being able to filter them out would make it quicker to find the recording made by the mini box which will probably be few and far between.
I'm not a fan of tiles in anything that uses them as the interface, but I think the Sky interface is especially bad, especially when compared to the likes of Netflix, Amazon Prime or Disney+ (which are not perfect either). I guess this is the Sky interfaces age showing.
I find/found searching useful for boxsets or catch-up stuff, but I'm not sure how much my parents will bother with this so searching probably not a big concern. I also hate the voice commands stuff on all the remotes that do that and can't see my parents using it either.
I prefer to let a program download completely after having downloads fail part way through and thus interrupting the program (on the old Sky+HD boxes), so want it to download quickly. Again, not sure my parents will do this too much.
I do wonder if part of this is that you've been using the Sky Q interface so long you're used to it, but I'm coming in fresh so I'm smashing headfirst into all these things for the first time and have examples of what I consider better and more customer friendly interfaces.
To make it seem a little bit more rubbish, they do support 5GHz networks but ONLY if you're using a Sky router. Using something else? 2.4GHz only for you. Crap, isn't it?
Personally I've hard wired both my boxes and disabled Wi-Fi on both via the hidden menu which has at least given me very stable connectivity.
Since my router isn't a Sky router I don't think I can connect via ethernet as I think without a Sky router you have to connect all the boxes or none of them don't you?
