Yes, this is just a portable software, so there is no desktop file, Because I cannot know which directory you put WindTerm in, I cannot configure the desktop entries Exec and Icon in advance. if you need it, please create it manually. If you have a better way, please let me know. Thank you.

编写一个脚本来适应linux的多种桌面环境的规则是一个不错的选择，但是成本较高；使用Linux的都是具有一定经验的开发者，所以我认为比较简单的方案是：在Linux的包中添加图标文件，我想大部分使用者都是可以自己创建快捷方式的，我遇到的问题就是缺少一个创建快捷方式的图标文件。

I am fully agree with you. I will place an 1024*1024 icon file in the next Linux version package to make it easy for users who need it. Thank you very much.

I am happy to inform you that WindTerm_2.3.0 has been released and a WindTerm.png and a WindTerm.desktop have been added to the Linux version, please download and check it, thank you.

BTW:
The WindTerm.desktop created by sakura1943 from archlinux, You can customise it to suit your needs.
