In past when I bookmarked a link I could've added description or notes to it.
the type of notes I used to add to Description field:
- where I learned about the website/link.
- What that page or utility does
- for some shopping sites, I would add the restriction of that websites, for example the minimum order, the locations they delivered to, what is the delivery cost etc.
- Specially if it is outdated website, I add Issues that the website had and workarounds.
It is just useful when you needed it. right now I add these to the Name field. But it is not that efficient .
