Comment 3 for bug 93378

Since this is now a wishlist item let me add to the above.

In addition to the problem with download not able to be cancelled, the really frustrating aspect is that the application is completely frozen waiting for all 1256 previews to download. This is bad design. Downloading should be happening in the background with the preview window progressively populated as images are downloaded. You should be able to work and even click to install while all this is going on. I believe this is called 'multithreading'. This application could probably use some.
