First idea is having different views for Opportunities pipeline so I can view different sets of data/custom fields within opportunities. My personal use case is that I have a designer who inputs design data and operations team who handles client approvals and order placement. Right now these are in different pipelines and different opps have to be created so data does not transfer from one opp to the next. Having different Pipeline views would allow for pipelines to be consolidated, limit the number of opportunities and data will not be scattered across different opportunities.
