Serious question: why use a tool like Figma that can capture so much detail? Don't you feel like it's implementing it twice? As compared to a napkin sketch that lets you see the detail you care about, but without less fussing to get just the right widget everywhere. Or do you just not go the full distance a design-only designer might, and do more of a just-the-critical-stuff approach in Figma as if it were a sketch? I used photoshop for this level, kinda specifically because it's not intended for this and I can't take it too seriously. I fiddle with and position the art, add some text boxes, etc, and squint a bit to see how it looks in broad strokes.
