Search capability to find an item inside of any action or process we create

Problem is when we create a really big workflow in a single action and we want to find one item where all it's used in that action. So for that we need scroll up and down to find.

For example above image, the time has very less item. Still we want want to search an item like ClassId. For that we need to scroll up and down if it's used some where @down.

So here to find that and going directly to that point looking for a search functionality.
