You want some substance? It started working and it is a disaster. I just tried to access my tasks via web version on mobile (can't use the app). It shows the new group button on the side panel. Actually i now see that it won't be as useful to me as i have anticipated as it seems it only allows to drag lists to groups, not individual tasks. Personally i don't use lists, just tasks. As i only use it for work and i don't have so many big projects to have lists. So, now when i press on a house button to get to the list of all tasks, i get the "list not found" error. Because there are no list. Maybe it will work in desktop web version. Though i feel that instead of doing work tomorrow morning i i will spend time trying to scrap my tasks out of this mess..
