Hi Stano
...
I believe zypp-devel is the proper mailing list for this.
Yes, thank you, they clared the question.
I append the patch, trying to resolve the enhancement in:
https://bugzilla.novell.com/show_bug.cgi?id=399239 - "YaST's software
installation modules should show disk space modification".

It adds the string " - Installing x MB" or " - Removing x MB" to the
tooltip on the "Free space" column (in the disk usage widget) .

The disk usage variation will work for the same packages that change
the disk usage bar; the zypp-devel mailing list pointed out that the
repositories with disk usage attribute are those soddisfying the
command:
dumpsolv /var/cache/zypp/solv/MYREPO/solv | grep diskusage


Here the patch, feel free to change (or throw away :)):
