Hiding Stories and User Stories in one board isn't a problem since the filters do a great job. The problem is that their sub-tasks still show up in this board.
JQL is missing the function to look up what issuetype the parent has. We tried the app "Scriprunner" and it works great, fantastic. For one single line of code the price is absolutely insane tough.
Is there another way to hide certain Sub-Tasks or does a free Add-On exist that adds the requied functionality to JQL?
