目前GoldenDict-ng的开始菜单文件夹名称默认为goldendict-ng-[版本号]。我不知道更新时安装程序会怎么处理开始菜单文件夹，第1种可能是新的安装程序不更改开始菜单文件夹，这样会造成开始菜单文件夹的版本号与实际版本不匹配；第2种是重命名开始菜单文件夹，这样倒是没什么别的缺点，就是看着比较丑；第3种是干脆再新建一个开始菜单文件夹，这样开始菜单里会有多个GoldenDict-ng的快捷方式。这几种方式都不怎么优雅。另外，很多用户需要桌面快捷方式，而安装程序没有添加桌面快捷方式的选项

Currently, the start menu folder name of GoldenDict-ng defaults to goldendict-ng-[version number]. I don’t know how the installation program will handle the Start Menu folder during the update. The first possibility is that the new installation program does not change the Start Menu folder, which will cause the version number of the Start Menu folder to not match the actual version; the second possibility is The first is to rename the Start Menu folder, which has no other disadvantages except that it looks ugly. The third option is to simply create a new Start Menu folder, so that there will be multiple GoldenDict-ng shortcuts in the Start Menu. None of these approaches are very elegant. Additionally, many users require desktop shortcuts, and the installer does not have the option to add desktop shortcuts
