I’m more than happy if the former two are done and dusted and my experience with BeOS and since on the former two has been pretty good. If something is pretty but not functional, people won’t use it. If something is functional but not pretty, it’ll get used nevertheless.
People might say it’s a false dichotomy but GNOME 3 and early Windows 8 are substantial examples of the opposite.
Windows 95 wasn’t pretty in any traditional aesthetic sense but by god was it ever functional and cohesive and successful despite basic bitmap faux-3D. Nobody cared.
Would like to try my hand at building something like that myself, but X on top of being phased out is a strange beast to learn and there’s practically no material on writing something for Wayland.
I've been working on and off implementing some Platinum stuff in Pharo's upcoming new graphics layer (called Bloc) and these have come out OK. That's where I'd really like to use it -- my whole desktop can be like Hypercard
You should look up the work of Sir_Cmpwn (aka Drew DeVault), specifically the wlroots project and his excellent writeup: https://drewdevault.com/2018/07/29/Wayland-shells.html
But I do think you're right in that if BeOS had survived, it would not look like that in 2019. It's probably time for Haiku to start evolving the UI/UX to keep current as the spiritual successor of BeOS.
The style is part of its appeal.
I think if they could get patches upstream for chrome and node, which would allow electron, that could open the doors for a significant increase in usable end user applications. The article's demonstration on progress for Java applications is very impressive on its' own.
Aside: being able to use user tweaked UI/UX would be nice in general, but would probably be a break from the BeOS origins. I used to run a shell replacement on Win2k and XP era, but I liked win7 so much I stopped using it (don't even recall the name right now).
In the end, there's no cause for rudeness here. While I don't think I'd be able to use Haiku currently, it's nice to see progress here. I'd also be interested to see a window manager for linux that followed the Be/Haiku aesthetics as I think a lot of people would appreciate it. Personally I really like the dock/taskbar in Win7 and 10, though I prefer the Win7 start menu. I run mac, windows and linux regularly (mac and windows daily, linux at least once a week on elementary).
If Haiku was a Linux Window Manager, I would use it in a heartbeat.
It's a bit of a stretch, but you could argue the comment goes against this guideline:
"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
