Creating Sub Tasks

Wow, I just spent 30 minutes trying to figure out how to create a subtask, just to realize...I cannot because I do not have an Enterprise version of this software. It would be VERY helpful to have a small popup message explaining this information exactly at the time I try to create a subtask...so that I don't waste my time and get a "negative first impression" from this software and pass that negative impression along to my peers. Checking the feature comparison page on the website helped me to determine the information I needed - only after clicking around and trying to complete the activity and then searching the internet for an answer. https://www.zoho.com/projects/pricing-comparison.html Feeling really disappointed.
