功能概述 | Describe the feature

我认为预览功能应该优先级高于emoji、表情包等功能，最好做一个和“登录”一样的按钮，而不是和其他组件同级，这样更醒目。

Feature Overview | Describe the feature

I think the preview function should have higher priority than emoji, emoticon packs and other functions. It is best to make a button the same as "Login" instead of at the same level as other components, so that it is more eye-catching.
