Skybox is great, the best VR app I've found so far, however a few things would really improve the PC client:
Search filter: This is simple, it cuts down scrolling endlessly to find a particular file for those who have large libraries.
A button or option to scan and then automatically remove redundant files: Files that have been moved or renamed still remain in the library and you have to manually go through each file to see if it still exists.
Some minor things: maximizing the window doesn't change the number of displayed videos, it's always a 3x3 grid. Perhaps make it scale to the window, whilst retaining the 3x3 as a minimum. Also having the ability to view the library in a list view rather than thumbnails, similar to the VR app, would be nice.
