It would be super helpful to be able to create relational fields on task layouts.

When added to the layout, you would pick the Zoho product/area for the field.

When in use, you would be able to search and select a single item from that other Zoho product, thus creating a link between the task and the other Zoho product (CRM account, Desk ticket, etc.).

Zoho Project tasks can do a lot of things, but seems to fall short with linking between other Zoho products.
