I'd like to help re-design riscos icons and perhaps improve riscOs UX. Where do I start?

Ctrl-click for Windows, shift-click or cmd-click for macOS.

Of course such a thing is possible, but it goes back to my earlier assertion. It’s a kludge designed to provide such functionality with the restricted hardware of yesteryear.
As Clive points out, RISC OS demonstrates an alternative that is more logical, plus removing the necessity to clutter windows with menus. The question, given three button scroll mice are commonplace isn’t “why isn’t RISC OS like the other systems”, the question is “why didn’t the other systems ever adapt”?

PS: I have barely played with MacOS, but how the hell did anybody get anything done with a one button mouse? And one that’s such a dreadful shape, too.

Correct.

But it’s true that the current themes are a bit old now. That’s the word every one tell me: “looks old”.
‘Modern’ OS use very simple backdrops and back of windows, with simple tools, and clean sprites.
We only have point 3 :)

And I good idea will be to have two themes: 1 dark, 1 white.

The perfect thing would be adaptive theme, as on old Fedora. Something that becomes darker, hour by hour. Perhaps a bit too much. Another idea would be to authorize some applications to switch from white to dark mode (a video player for example).

I find the very idea of a mouse ludicrous. Okay if better things didn’t exist, but they do. A Marconi Trackball (with three buttons…) was always better; and a trackpad is better still (although I do wish it had three buttons as well – and would work with the Pi…)

But does that result in a better UX? :-)

they’d need to keep up to date with file formats for compatibility

Seven hours since Clive posted this.
I’m a bit disappointed that nobody has stepped forward to suggest XML as being the magical solution to all of the world’s file compatibility problems…

:-p

Do you enjoy scoring cheap points or something, Rick? 8~) Or taking pot shots at easy targets?

Easy target. ;-)

I threw something together to see how my themes would work under the new scheme. It’s not perfect but might provide a useful starting point, you’re welcome to it if you want.

Oops – missed this! Sorry Fred, that would be great. Do you still have my email?
