For those who are not able to use it: Pixiv updated the UI weeks ago and made the script fail. I have fixed at least the labeling function presently and the rest will be checked later.
The script has run for years and is entering a slow maintenance phase. But I will keep on it, and try to improve it when I am free.
致日前无法使用本脚本的用户：Pixiv几周前更新了UI，导致脚本失效。目前我已经恢复了标签功能，其他部分能否使用我会在稍晚进行检查。
本项目已经运行了数年，目前已经进入低频维护状态。但我会坚持跟上官方更新，并且会在有空的时候进行一些深度更新。
No problem, thanks very much for your hard work on the script. Looking forward to anything that may get added in the future.
