Chris and Wayne,

I have the latest nightly build and I can confirm a slow-down when I try 
to add a component in a schematic. The first usage after KiCAD startup 
takes roughly 3-5 seconds to load. Every other usage takes approx. 0.5 
seconds and it is quite annoying and productivity killing.

I was used to that in the stable KiCAD (4.0.7) the first library load 
takes a while, but after that the component chooser opens automatically.
