HubSpot has allowed admins to add custom properties to more objects in HubSpot like Workflows and Lists, which is extremely helpful for admins. Unfortunately, Forms didn't get the same additions. Forms don't even have a default description property like workflows have had for a long time.
These custom properties are very valuable to admins to manage the clutter in these objects in HubSpot. If these properites are available in workflows, it opens up even more possibilities to automate actions based on these properites.
At the least, I would settle for a default description property. If I could add a description of where a form is used and when it will not longer be used, it would decrease the amount of time I spend trying to track down how people are getting linked to forms and whether that form is still in use or not.
