Appreciate the feedback, and I agree. The image (and news for that matter) search tabs are now kind of just a box check, but they are both on the roadmap to built out to be made much more usable. Adding a dark mode will be pretty simple and I can add it to the list.
I wish something like the Web Monetization API [0] was a viable path to monetization, but I don't think it is in the current state.
I believe the only current path to monetization that preserves user privacy is context based display ads that work like billboards in the real world. I am working on that now, but the idea is a flat fee to display the ad for N days regardless of views or clicks.
