Initial Summary:
bad column width allocations in Installation Summary

Y2logs: https://bugzilla.opensuse.org/attachment.cgi?id=808684

Applies also with 15.1.

"Summary" is arguably the column that needs the most width, yet it gets the
least. Installed(Available) and Package both exhibit an overabundance of
whitespace. To correct the problem requires first moving Size well to the left,
so that Installed(Available) can be moved to the right without making Size
disappear offscreen. That's a lot of mousing and dragging that needs to be
redone each time returning to the Installation Summary tab from another tab.
