Make a 'parked' option for action items and a tick box that showed them, rather than a tick box to hide (action item list too long) Merged

My action list is full of things that are on hold but not relevant anymore but I don't want to mark them as done as they're unlikely to to be. I'd like to see a  'parked' option for action items and a tick box that showed them, rather than a tick box to hide.  OR Add a tick box for actions 'on hold' so they can be filtered from list
