On the 'jarring' action - what is currently happening is that selecting triggers
the form and the 'current selection' is kept track of in python.  It would
likely be better to use javascript during the entire selection process (thus not
requiring a reload) and the apply could read the whole table.

On the multi-select, that would be nice.  I know it requires some (I believe
fancy) javascript but not sure.  You (seth) wouldn't happen to know how to do
that offhand, would you?
