Hi everyone!
Thank you for your thoughts about this feature request! I just submitted it to our Product team and will let you know when there are updates on its status.
I will continue to monitor this thread for additional votes or testimonials.

Any update on this? I see today in the online presentation that Lumerical now has dark mode. How about Optics Studio?
This would be great, especially for us night owls.
Hi everyone! Thanks for checking in 
. I just heard back from the Product Manager about this.
The development team is actively working on dark mode for OpticStudio! We don’t have an official release date yet, but we are working on ensuring we are aligned with other Ansys products with respect to this functionality. So stay tuned - we will notify this thread the next time there’s a significant update.
