When we select the application and press "More Info" button we can get information about the app. A lot of applications have more than one images uploaded by developers. And it's very inconvenient if you want to zoom these images and view them. You have to select one image, zoom it (appears a window), then close the window, select next image, zoome it, etc.

When opening the ubuntu software-center, the program retrieves a list of available software (ads) to show. While this is going on, you cannot write in the textbox. So, if you already know the name of the software you want, you have to wait 5-10 seconds before you can even start searching.

This should be easily solved by putting the focus on the textbox on showing the window.
