In addition, it would be beneficial to at least have the option of displaying the latest object links of tasks in the columns (e.g. as a task linked to services, offers or meetings). At the moment, it is only possible to display the connections of deals, tickets, companies or contacts.
Agreed it would be amazing to get more customization on tasks. Also decision on what properties to display on the task activity on the records. Like Phone number of the associated contacts.
Please add this functionality! Tasks have properties, so it only makes sense to be able to see/edit them. They are not currently listed in the “properties” section of the settings, but they absolutely should be! Also, you can’t see who created a task on the task itself 
Great idea! I’m already running up against limitations with Tasks. Would really like the ability to have resolution statuses and create custom priorities to start.
+1 for customer need
We definitely need this as well! Would make a huge impact on our task handling process. Especially because it would allow us to inform the task creator about the completion of the task (automatically)
Hi everyone,
I’d like to thank you all for taking the time to submit, vote and comment on this Idea. My name is Mark, and I’m the PM for HubSpot’s Tasks
I’m happy to announce that this feature is now in a Public Beta. You can test it out by joining the Beta for Custom Task Properties & Subtasks. We also recommend joining the Beta for Tasks App Refresh to access custom properties in the Task Index page.
