Hello, I just started experimenting with Vikunja and registered here to basically ask the exact same question. I feel that the default behaviour for the “Upcoming” tab should be to show only tasks that are past the “Start date”. At the moment, when I have recurring daily task that I have completed for today, it will immediately show up again in the “Upcoming” tab even though I can’t even work on it until tomorrow.
I don’t know exactly what the “Start date” is currently used for, but I’m using it to mark the date after which the task is “workable”. If the task is not workable, there is no point in even showing it in the task list, right?
