For those that draw print-ready white background is essential.
I know I can change the color from Rhino.Options.Appearance.ViewportBackgroundColor but print-ready is very important for many users and could be good to have a dedicated command for them.
You can also create a custom display mode with a white background for this purpose and just select that.
@Helvetosaur I already have a custom display mode for diagrams , which I would also like to propose as a new display mode.
But my main idea is to have Rhino more friendly for drafting and printing and for diagrams. The ingredients are already there, they just need to be a bit more advertised…
maybe a new Toolbar with WhiteBackground, PrintDisplay, SetDisplayMode Diagram, SetObjectDisplayMode, Line Weights settings, LineTypes settings, Shadows, SunLocation, CaptureViewport, SurfaceEdgeSettings. These are the main tools used.
I think the topic title should contain the words ‘wish’ or ‘suggestion’ otherwise it seems like an announcement.
Also, it’s more convenient to work in shaded and then switch the background to white to check how the drawing looks for print. therefore, a command would be nice.
The “Shade” command does that. It’s useful for a quick ckeck. You can assign a custom display to it.
Again, you can make a copy of shaded and change the background to white. You can put it on a button or create an alias for it. Or use the Shade command as stated above.
Going via Appearance>Colors>Background is global for all instances of Rhino you have open and is also sticky between sessions.
The fastest way for me is to make the background white and use gradient view, as below.
But I don’t want to make these settings or any settings and I don’t want to explain those settings 100 times to the people I work with.
As we have gradientview from the box we should also have whiteview.
Get better people.
It’s not about the people, it’s about the user experience of Rhino. It’s counterintuitive to make such settings for having a simple white background.
You already have that functionality. To access the hidden command-line options type
-GradientView
and change both gradient colours to white. 
GradientView (activates/deactivates the gradient background)
-GradientView (opens the Command line settings)
@Rhino_Bulgaria , as I said before, I don’t want to make any settings. I want white background option available by default.
I understand, but once you change the two colours to white, they remain white for the next sessions, too. At least this is how my Rhino 7 behaves. 
@Rhino_Bulgaria yes, i know that.
But I want Rhino to offer a very friendly user experience for those who draw for printing. Because it’s a bit behind on this point. And a very small thing to offer is a white background option in the next version.
I agree with that. It could help the people who often do printing on white paper. The functionality is already there, even though it’s now a discontinued (hidden) command replaced by the custom display modes.
There was a discussion in another topic about the missing commands that sometimes are not included in the toolsbars, but exist in the text menus. Or vice versa.
yes @Rhino_Bulgaria everything is already there. All it needs is just a clean user interface, a toolbar with a few buttons can make a big difference.
