Hello, 

I have a suggestion which i think is very easy for your team to make it happen.

When you look to a blocked task by a predecessor task or you look to the predecessor task what is next you have to copy-paste the title of the task to zoho projects search all modules tool to find them. You can make it a hyperlink to the task so we can find it with just a click. See image bellow

I think that is something minor that makes the difference for advanced users

thanks
