Dark Mode for HealthShare Management Portal - Visual Accessibility Need

Hello InterSystems Community,

I hope you're all doing well. I'm reaching out to ask if there's any way to enable a dark theme or dark mode for the HealthShare Management Portal.

Background

I have a visual impairment (amblyopia/lazy eye) which means I'm nearly blind in one eye. Like many people with visual difficulties, I find that bright white backgrounds and interfaces cause significant eye strain and fatigue. This makes it challenging to work with the Management Portal for extended periods.

What I've Found So Far

I've searched through the community forums and documentation, but I've only found discussions about dark mode for InterSystems Studio. However, I specifically need to know about dark mode options for the HealthShare Management Portal (the web-based interface).

My Questions

1. Is there a built-in dark mode or theme option for the HealthShare Management Portal?
2. Are there any configuration settings or CSS customizations that could achieve a darker interface? (I can enable dark theme in Web Browser, for example Mozilla Firefox but it does not let me see the Management Portal in dark theme).
3. Has anyone in the community found workarounds or third-party solutions for this accessibility need?
4. Are there any plans from InterSystems to add dark mode support to the Management Portal in future releases?

Why This Matters

Visual accessibility isn't just about personal preference—it's about making these powerful tools usable for people with various visual impairments. A dark mode option would significantly improve the user experience for those of us who struggle with bright interfaces.

I'd greatly appreciate any insights, suggestions, or experiences you might have with this issue. Even if there's no official dark mode, I'd be interested in hearing about any CSS modifications or browser extensions that might help.

Thank you in advance for your time and assistance!

Best regards,

Yone
