When installing packages from a ftp-source, progress is shown in two tabs, the 
bottom one contains the package-names, once with the size that needs to be d/l 
and once with the size they need when extraced. 
In the top tab, there are columsn for media, size, packages, and time. It 
would be noce to have a columen "Download Size", in order to estimate the 
amount that has to be d/l. If for example installing big packages, like 
kernel-sources, the actual-size and the size of the package differ quite a 
bit.
