Totally agree. I’m just creating a new Deal Worflow for a client, and hadn’t realised that only Contact Workflows only allow you to add a Description! That’s a bit crazy and not very consistent as a user experience 
I would also like to be able to display that Description as a column in the Workflow View, so it’s much easier to interpret the impact one Workflow may have on another.
Please can we add this VERY soon, HubSpot!
