当我需要制作一张海报或打印文件，我可以直观获取实际尺寸。WHY NOT ILLUS OR PS? ILOVEFIGMA ! figma画板很大，很流畅，很顺手。illus没办法创建太大的画板，ps运行太慢！
比如我现在需要制作A4尺寸文件，我会创建210X297px的框架，导出后适应A4纸张打印，他能工作！但是如果能直接修改像素为毫米单位，那就太方便了
When I need to make a poster or print a file, I can visually obtain the actual size. WHY NOT ILLUS OR PS? I LOVE FIGMA! The Figma drawing board is very large, smooth, and very convenient. Illus cannot create a drawing board that is too large, ps runs too slowly!
For example, if I need to create an A4 size file now, I will create a framework of 210X297px and export it to fit A4 paper printing. It will work! But if you can directly modify pixels to millimeter units, it would be too convenient
