I bought this bookmark organizer. I played around. I was not certain that it is a good solution to use it. But I am pleased now. CNAME works for me. I was able to use all the white-label functions and nevertheless I could upload my old bookmarks from other account.
It is also easy to handle the size of the icons. For my taste, it should be possible to increase the size of the icons. It is perfect to have the possibility to use own icons. It is a saver for me!
