you can also edit the filter, remove all the columns you dont want to see, save the filter and voila ! you dont see any more the columns you dont like.
Wait - i think i know what you mean, you are using the project menu shortcut for “Tasks” that opens a window rather than the Task tab right ? that window does not include the filter option - is that what you mean?
2/ we add columns that list all audits as a number, we have a similar appraoch on the online assessment questionnaire … when you click on the number you get redirected to the tab with a filter pre-defined.
we will include a column with the counter of related (tasks in this case) , when clicked it takes . you tto the filter of tasks. this logic will be applied on every section with child sections.
