1.Request having a library like pixivutil.
2.Request save folder can be named like D:\Data%searchtag%.
3.Request Downloading new illustrations from some searchtags at background.
4.Request Downloading origin image if source is pixiv.
Sorry for my mistake
Thanks for your reply.
2.I mean that the file can be classified management by tags, rather than the Format Filename have questions.
4.I hope that in full batch mode if source find ("pixiv"), then there is a classification, to prevent it and the pixivutil downloaded files repeat when the author was the same artist.
