If I have my library open in Artwork view (grouped by artist) and I begin typing (not in search box) MB does as you would expect and jumps to the nearest matching artist. e.g. I type N-A-T and the view jumps to 'The National'. Perfect. What it currently does not do is highlight that artist. When you have many artists on screen you have to visually scan the screen to actually find what you were looking for and click. To me, it would seem logical if MB automatically selected the best fit / first match of whatever you started to type.
