Oh man, I was the same way for ages, stubbornly nudging things pixel by pixel. Then I watched someone use auto layout once and it felt like actual magic. Now I just group icons and let Figma space them out perfectly every single time. It saves so much headache on those big sets.
Exactly, it's the difference between fixing it once and fixing it every single time. Auto layout turns spacing into a rule instead of a guess. Once you set it, you can forget it.
