The main function of the app being discussed here is to draw solid black rectangles on the screen.
Don't forget the "average person", I'm assuming someone relying on software as a tool, doesn't care about the stuff "designers" seem to obsess over, and will actively hate if you break their workflow by doing things like adding useless padding that makes them scroll more or shows less information in the name of "modernity". There's a lot of specialized niche software for various industries, often very expensive too, which looks like it came out in the early 90s. As long as it works well, users won't complain.
Would that UI be hard to accomplish?
Win32 provides its own components which are basically Win95 style apps, and you can draw the components using some graphics APIs by yourself.
The whole native development area is a mess exactly because making your own (decent) renderer is a huge undertaking.
I came from the WinForms world so don't pretend I don't understand Win32 programming. The fault lies with Microsoft for not investing in it more.
Flutter is nicer to scale and maybe design but it is a massive overhead. Skia still has trouble with some drivers and causes lag or falls back to software rasterization. Hot replacement while coding is pretty neat though. It runs much better on mobile devices imho.
But that "modern" style is... disgusting and repulsive. That whole dialog is bigger than one of my monitors due to how much wasted space it has.
We did a UI refresh at one point. It looked much nicer. People hated it. We had to hastily redesign it again and it looked far more like the original.
Case in point, the Dropbox Simplified Desktop App was a huge improvement for me. It nails just about everything I ever needed their app to do, and removes all the user-hostile fluff I never asked for. Similarly, I found Windows 11 Enterprise IoT LTSC to offer an improved desktop experience compared to traditional Windows, thanks to its exclusion of a lot of the cruft Microsoft otherwise shoves down the throats of users who, as far as I can tell from frank discussions with many of them, likewise actively don't want.
I'm not saying your desire to make your app look polished means it's crap, but beauty is in the eye of the beholder. Just like fashion, I wouldn't be surprised if we see a shift in the aesthetics trend as more people discover a retro feel sometimes signals a better user experience.
Several integration points like this have been removed, supposedly because third party software was just too bad in how they used them, causing issues. Or at least so goes Microsoft's perspective. Personally, I find that very believable! If by integration points the only thing one can imagine is calling into random third party code on the regular that the user has installed, bang spank in the middle of critical user flows, on the same thread and in the same process as itself, that's exactly the kind of grief I'd expect to occur...
If only there was a way to provide a way to craft e.g. custom flyout menus for the taskbar or custom pages in the Settings app, without invoking arbitrary third party code and possibly causing crashes and hangs in system apps and menus... or just not letting crashes and hangs affect the application (e.g. Windows Explorer) calling them in the first place.
Then there's the removal of title bars from Windows. You often have no idea what app you're looking at. Pull up a PDF in Acrobat and also in Edge. Now, at a glance, which is which?
Regressive garbage.
they did what??? [i'm still on 10 because 11 won't run on my laptop </3]
