As someone who posted several times in the various eye candy and related threads I am for more / full customization. Yup, you bet'cha
But if JRiver decides to do that, I am guessing it would be a major feature over haul, and would, at best, be in version 18.
So, for version 17 #4 is a great improvement. Like one of the other posters mentioned, it would be good to have some similar examples for video and images and the like. Those views need layout improvements too.
If, by chance, it is possible to allow for some choice in views in version17 then +1 for InflatableMouse. Put in an option to let us pick the one we find most appealing.
