Hi - Why is the Fluid tile named as Simple Journal? I see that the Fluid page allows entering more than 2 lines in the Journal and we can use more than 2 accounts. So wondering why this is named as Simple Journal? Are there any limitations when we use the Fluid Simple Journal as Opposed to the classic page to create and Update Journals? How does the Fluid Simple Journal differ from the classic journal entry in terms of the functionality offered?

Suppose we have not been creating Simple Journal Types and Simple Journal Templates, is this Fluid Simple Journal tile not useful for us?
