Hello,
We recently noticed that new canvas dashboards default to a new look - the Vanilla theme instead of the Classic theme. I like the Vanilla theme better, but for consistency with our suite of dashboards we need to stick to Classic for now. Is there any way I can set the default theme for everyone in my organization to Classic? I didn’t see anything within the visualization settings.
Thanks,
Becca
Hi @Becca_Perry, thanks for the feedback!
Currently, setting a default theme for your organization isn’t supported yet, but the good news is that this feature is on our roadmap and your request has been documented. We’ll keep you updated as we make progress.
In the meantime, you can use the Code Search feature in Development to bulk update the themes of existing dashboards. Just search for theme: H.themes.classic and replace it with theme: H.themes.vanilla as needed.
Hope this helps! 
Hi @Becca_Perry,
I’ve converted it to a feature request so others can upvote it as well! 
As we’re exploring this feature, it would be helpful to understand more about your needs. Could you share your thoughts on which user roles should have access to this ability (e.g., Admins, Analysts, or all users with access to Development)?
Thanks for your input!
Thanks Theo!
My thought would be admins, similar to Chart Color Palettes and Default Records Limit. Users with access to Development mode can always override it on a one-off basis via the report, but I would think that site-wide defaults should be pretty limited in who can change them.
