I suppose there is some 'logic' in disallowing duplicate bookmarks in the drop down folder structure, and I know the 'one bookmark' restriction is several years old and related to tags, which I don't use. But it often happens that I find myself going to one or several web sites frequently over a limited period of time. It was very convenient with IE to duplicate those 'high use' bookmarks in the menu bar for an intermediate period. With IE, I did not have to delete those bookmarks in the regular drop down bookmark folder structure in order to add them to the menu bar, and then later on have to reverse that process so as to have the bookmark somewhere in the folder structure, given that I was deleting the toolbar bookmark. I don't want to use a sidebar. In other words, bookmarks chosen for my menu bar were functionally dynamic, so to speak, and wonder if the trade-off for tags remains generally a good idea.
