Hello,

It would be nice of adding books could be faster. Small works on a decently quick SSD might take 3 or 4 seconds though larger books that I often add such as a test of a 400 meg EPUB takes 35 seconds. It seems that calibre is unzipping the whole file when I think all that's needed is the container.xml, OPF, and the cover. At least in cases when a large book takes a long time to add, the abort button doesn't respond until processing is completed, and in one test, the book is still added. As I often add large works, it would be nice if it were quicker.

A few bugs with 4.x. The adding books dialog on macOS has a minimum width of around 1050 points. Maybe that is 2x retina or something. And dragging out a multiple selection to copy books out of calibre no longer works.
