My colleague asked me to add Gannt chart to his project. I found BigPicture plugin that is used by other teams and created a box for him. Now I sit and watch how bigpicture adds Auto bottom up value to some custom field that cannot be switched off to 12 000 issues, 95% of them are closed decades ago. It already took a couple of hours and I guess it will take 10 more.
Is it some kind of best practice for BigPicture boxes creation?
