Over the years, I've been a fan of most of Figma's updates, but the recent ones have been somewhat disappointing to me. The notable exception is the flex mode, which seems to draw inspiration from Penpot.
As for the developer mode, I find it lackluster. Its primary value seems to be in its read-only mode. In the past, I addressed this by copying deliverables to a separate file to prevent accidental edits.
Lately, I've observed more and more designers with coding skills or coders with design skills. When I work with people that they understand both worlds, I prefer workflows that incorporate Figma and Storybook, emphasizing code as the ultimate source of truth. I'd like to see more in this direction where there is no artificial barriers between coders and designers...
