For myself, the task numbers bear no relation to the order the tasks get carried out in, they’re essentially just visual clutter on the kanban tiles.
(I know Kanboard does something similar - but it uses the number as a hook for a quick access menu.)
I know Vikunja table view allows sorting by task number.
My question remains, does anyone find it useful to sort by task number in the table?
Does anyone find it useful that task number is shown on the kanban tiles?
