Patch below fix this, but we stumble in another problem, when zooming it
is not eliding the SOCKET column, i.e. if we're zooming into a column,
it will have the same value for all entries, no use in showing it, save
some columns, will check that as well.

Will fold the fixes to the patches where the problems were introduced,
the feature is cool, one more zoom! :-)

Thanks,
