Musescore 4: Where can I enable "continuous view"?

Holy cow. This reminds me of when Sibelius overhauled their UI. Supposedly many people quit using it because they didn't like the changes. Of course people are perfectly within their rights use whatever tool they want. But button location complaints seem a little over the top. I get it. You get used to things a certain way. then it changes for no good reason you can think of. Sorry but, oh well. I switch between notation programs often. Most everything is in a different place between them.
I'm not interested in defending MU4. I'm just wondering why after more than a year, people who prefer MU3 don't just stick with it.
I found the comment that the sounds don't matter.....interesting. Sure, if all you do is transcription, maybe. Or you have perfect pitch and know, in your head, exactly how things will work together. And yes, the sounds are only to give you an idea of how the piece will sound. I which case, all you need is a piano sound. Or even the original GM sounds (argh). I write for playback. Yes I know, I should be using a DAW and several thousands of dollars of sounds. Yeah, that's not going to happen. When I open one of my pieces in different software, guess what. It sounds different. For example, I wrote a piece in Sibelius. Which has 35gigs of great sounds. It sounded OK at the time. When MU3 offered SND I put that piece into it. I had to rewrite things that didn't work well with the MU3 sounds. But it was fun to experiment. But it didn't sound as good as Sibelius. This piece has quite a loud almost bombastic climax. I had been experimenting with MU4 in beta. After Muse sounds came out I decided to try them out on the above mentioned piece. I loaded the mxl and made sure everything was on Muse sounds. No other adjustments. Then I hit play. Playback through the first part was better than MU3. But that isn't saying much. Then we hit the climax part. It was spectacular. Powerful with lots of punch that even Sibelius lacked. As a result I don't have MU3 on this new computer.
I learned long ago to not rely on the save button. I don't use it. Or a bunch of other things that are "missing". It's all in how you look at it. For me adding back the things the way they were in MU3 would be a regression.

Is MU4 perfect? Hardly. Many things in Muse sounds seriously need to be fixed. Is it better than MU3 or Sibelius? Not for me to say. I use whatever program does what I need at the moment.

Making “it has to always keep looking the way it has always looked” despite all evidence from standards and actual usability testing pointing to the fact that it’s always been bad design is, well, bad design. Like it or not, when a design isn’t good to start with, changes are necessary to make it better. There is room for honest disagreement on the specifics of course, but it has to based in something more than “ just it’s always been this way, and I don’t like change”.

Sounds to me you haven’t performed usability studies of your own, nor do you appear to have extensive experience in user interface design. But if you have some actual informed data to bring to the table I’m sure it can be considered alongside the informed data from the user interface who have done the usability testing thus far, and further improvements may be possible.

re:missing features
I'd chalk it to the seemingly rushed release date, but it's a good move considering ms3 users were starting to feel frustrated waiting. On the other hand, the beautiful horn that comes with the new musesounds definitely boost dev team's morale, which is crucial to all other good features yet to come. The improved UI's gonna attract more talented musicians and speed up dev. It will shape up to be the killer app that kicks even dorico's assthetics and become the dream notation app, free of charge. Everyone will use it. As long as he also has ssd.
