[Feature Request] Hide Dock Icon

[lightumcc]

Great app! It solved my anxiety about clipboard privacy. But currently, he takes up an icon in my Dock even when I don't have any windows open. Hopefully, you can fix this sometime.

真是非常棒的应用，他解决了我对于剪贴板隐私的焦虑。但是目前他会在我的Dock栏中占用一个图标，即使我没有打开任何窗口，希望您有空可以修复一下这个问题。
