I've watched the video, it intrigued me and left me with these questions: Can you put an item in multiple collections at once? Can a collection be inside another collection?
Thanks! We used to support nested collections and 'single item - multiple collections' in the intermediate versions, but decided to disable it for the overall simplicity of the v1. We'll bring it back when/if many users really want it.
Let this noisy wheel add a little squeak... I would (could) not use it without the option to store a URL in multiple bins. I use both nested folders and "aliases" right now... (drag and option-cmd-drag weblocs into one or more folders on my desktop)
