建议增加备份功能

[YesHub]

条目如果多了，很不好管理，建议增加导出导入功能。 最好增加为每条链接增加注释项。

English translation of the issue's description:

If there are too many entries, it is very difficult to manage. It is recommended to add the export and import function. It is better to add a comment item for each link.

Good points, YesHub!
I'll address them when I have the time.
