Hadn't considered there to be an option.  When I looked at the
PatternFly demos I hadn't thought about it, but the speed that
FreeIPA pulls data out for rendering, I suppose it would have to be.
Even our modest estate (at a few hundred users and hosts)
would slow down far too much if the full dataset was sent.

The other possibilities thrown up by PatternFly are also interesting;
add/remove columns, resize columns etc.  I know some of
these are still on the drawing board, but there are demo pages available
already.

True. What's the biggest time factor in loading large tables?

When admining estates with tens of thousands of entries, however, much
emphasis needs to be placed on the table filters. No
admin in their right mind is going to be performing actions on all
entries simultaneously.  Similar to Foreman's filters, could
FreeIPA allow (example) in the hosts screen a filter of "hostgroup =
groupX" to show only hosts belonging to that group?  Or filtering users
with "manager = 'Duncan Innes'"?
