We have recently enabled linking CTA to Opportunity and this feature is fantastic! The current ask is for this linking to be established between Opportunity tasks and CTAs. Right now the tasks created in the CTA sync with the Account object instead of the Opportunity object in question. Ideally we would like these tasks to sync to the Opportunity in most cases so activity tracking and next steps are clearly linked to the Opportunity they are associated with. This will be especially helpful in cases where Opportunities are handed off so the associated completed tasks and pending tasks are clear to the team member that takes over.
The next ask is that if someone creates a task in SFDC on a linked CTA, that task is merged into the CTA as well. This might be a tougher ask but certainly worth mentioning. If one or both of these asks can be incorporated as an option on the CTA that would be great!
