I've not found a way, though another thread says a program Bookmark Manager, does so.
Also, I've discovered the sort order selection for bookmarks on the browser, defaults to "newest", if you reboot your Incredible. My desired alphabetical sort setting reverts to the default. :/
Tip: I've added a "*" to the beginning of the title of my half-dozen, or so, favorite/most used bookmarks, to position them at the top of the alphabetical list.
