As stands, the Commentary feature only has fields for the title and description. However, I have been adding the date-stamps of those same sources in the latter field. I see the following values in this practice:
Further "bookkeeping" (many details are tagged in an image file, but the following point may apply between an image and its source page)
- Discrepancies between upload date/order sources and Danbooru
- Context for post and/or commentary
- For posts from single multiple-image sources (primarily Pixiv: "Manga xP"), draws attention to sibling images, especially if not uploaded to Danbooru
- (Tangentially, providing a date-stamp would carry with it what commentary may exist, even if just "Untitled", removing later uncertainty of whether any commentary existed at a defunct source. Not that I demand a Commentary regardless of significance, just there may be meager value if done.)
In absence of a specific field for this information, do other users also find value in providing this information in the commentary description field?
