RFE: taskopen -C ['column definition']
-C as in Columns

With a default definition in .taskopenrc

 columns=$CHOICE) $ANNOT ("$DESC") -- $ID

then just

taskopen -C

would use the default order, aligned in columns, and 

taskopen -C '$CHOICE | $LABEL: $ANNOT | $ID $DESC'

would override that order.
