@pafflick thanks again,
some people make their lives difficult, don't bother trying to understand.
Mainly the question was "did I overlook something? Or is it simply not possible?" The answer was "You're correct, that is not an option." Well, let it be.
On the other hand, would it be a nice feature if everyone could have a bookmarks-directory shared with others using a cloud share? More like a chatroom. You make a shared list by a name. I share the code with someone I want to give access. From that point the two of us can add bookmarks. Would be fun, I think.
I'll see where I end up, again thanks for your efforts! Cube.
