Hi Diego, it's very interesting! But also a huge amount of work to make something like that.

It looks like that bookmark concept is someone's research project, they may have spent something like the last year working on nothing but that.

I probably just cannot afford to spend an entire year's worth of time just on this one feature area of MoI, so I probably won't be able to do something as cool as that, but there are some concepts in there that would be good to keep in mind.
