This is purely subjective, but I'd prefer the top main cards to have darker background colors. The Banking one is perfect, but the others are a little too light, making the text a little harder to read than necessary.
@simplij This is the place to make your preferences known. Anyone else find those top panel summary cards too light in color to be readable? (Especially the green one with your Net Worth)
I might be wrong, but I believe Simplifi was build with Google's Material Design components which have built-in dark-mode color styles. All that to say, it might be low effort for them to have support for Dark-Mode.
+1 for Dark Mode
