I see that there has already been a suggestion to allow the resizing of the Mac player. Can I add to that the option of various skins so you get the greatest visibility on your monitor?
I have a 30" Cinema display 2560 x 1600 10.9.5 running Vox 2.4.1 build 2410.370 with loop support. There are are a number of issues with the player window:
1) The Album covers are so small that text is unreadable.
2) I have always found that white on black may look elegant, but it is much harder to read. This may be a personal thing but if you look at the screen shot the bit rate information is at least for me virtually unreadable, whereas the finder fields which have about the same font size are quite clear. It also may be an issue with the font that is used. Thus the ability to resize would be a workaround, but the ability to use a different skin would be better.
And when I move to a 4k or 5K display .... ?!
