Long shot, but figure I might as well ask: different users no doubt have different parts of the inspectors that they are keen to see all the time. E.g. I want to see backlinks and annotations, which currently can’t be seen at the same time.
If there were an inspector pane that could be customised that would be awesome. E.g. it’s possible to drag and drop items into the toolbar to create a personalised toolbar. Imagine an inspector pane that allowed drag and drop of the various existing inspector components. I could then drag the backlinks control to the top of my customised inspector, the annotations control next, and then maybe a couple of my custom metadata fields.
