Just FYI, I recently came across Figmiro in Figma. It’s basically a plugin you can use mostly the same way as the Sketch plugin. So, essentially you can re-export all your frames and keep the connections of your flow or any other changes you may have added. It’s not perfect but it’s certainly a live-saver for me. I no longer see a need for my previous tool: Overflow.
I only wish it exported better-resolution images but I can’t complain. Thanks for this, Redmadrobot! (https://github.com/RedMadRobot)
