I don't like how in the new version every time I want to add an image, the image library takes a few seconds to load. The old version just came up. 

Also the old version had a preview window so you could click a thumbnail and see a larger preview of it and how it's drawn. 

The thumbnails in the new version are really small so it's kind of annoying/time-consuming to have to actually  insert the image in order to see what it is. 

I would love it the image library to work the same as it used to. I don't find this new setup an improvement at all.
