A: Happy to see you like Marvin so far.

In the productboard there is a button on the top right where you can submit your own ideas/requests. It's turquoise. You can get to the productboard from within Marvin -> question mark on the top right, then "Submit Idea/Feedback"

There is a dark mode. If you go to settings (top right) then themes, you can select two themes and toggle between them in the main view with "O" anytime.

The themes are stored locally so if you use Marvin on multiple computers configure it on each. This is so you can have a different look at home vs. at work for example.

We are working on new mobile apps, once we have the new design there we will add dark mode on mobile as well.

Thanks for the support!
