I only just started using/testing the Win Beta, so I might be missing something, but I don’t get how colours are chosen when one adds a new keyword to the list. It seems to be a random choice that doesn’t help to group things at all.
Unless I overlook something, it would be desirable to have a more structured assigning of colours. In particular the ‘child’ keywords would logically take the colour or a tint of the ‘parent’ keyword.
Maybe picking the colour from the currently active (clicked) keyword for the new keyword would be a way to go.
Another thing that might have been addressed already is the delete function. Even though I am navigating in the keyword HUD and trying to delete an active (clicked) keyword entry, hitting the Del key moves my open document from the research folder into the recycle bin.
