The most prominent thing is non-editable auto summary that can be hectic, boring and redundant if you make a notebook. There is no need to fill half of your screen. - I would like to be able to move it and have bigger notebook than auto summary or at least edit it (delete/highlight/rewrite parts of it).

I suggest placing the notebook on the left instead of non editable auto summary and moving auto summary on the tabbed right part so that it can be "hidden", and not the first stuff we see - visually it is much nicer to be able to return to the curated content than to the auto summary.

Even better - make it possible to choose what can we put on the left and what can go on the right (eg. to be able to have notebook and connections visible in the same time) - and the rest is in tabs, as are now graphs etc.
