The current printout of the Advanced Search is not formatted in a manner consistent with the screen. So it is not true WYSIWYG. In addition as I understand it, their is no hierarchy presentation between parent and subs. In addition, it shows all the comments. A number of people want to see only the simple list. With your new information I understand Sections better but not sure how they can be rule based to an automated report. Here are three examples, My Tool I am Trying To Develop, Asana Hard Copy Printout and Screenshot of Search Results .
All three have there issues. Asana hard copy and screen do not indent for subtasks so there is no distinguishment. My report cannot report Sections because they are treated as a task with a colon but can't be connected to the task associated with them. They are a problem especially if you use a fixed sort of Project, due date as you don't want to show a section break at every due date. I think rather section would be a column. Your reply again has been very helpful as I think through this. I want a very automated process with a fixed sort, there will be no sort options other than by Project by Due Date, but the Advanced search will allow much flexibiity as to what you request and who you request but I hope there is consideration for a column in the CSV for sections in the task that fall under them.
