I tend to not use bookmarks in browser because I switch between machine and browsers a lot. I keep my bookmark online on my own site. However there are times a quick bookmark saved is useful. Opera is my browser of choice. Their bookmark interface is, well, brilliant: To add a bookmark to a sub folder in your set of bookmarks, you navigate to the folder, and at the top of that folder display is a Add page here... item. If you click on that your current page is added to that folder. Brilliant ! So they are mixing data with action in the same window, but it makes perfect sense.
