Sounds logical.
My thinking is this though: You can do all bulk changes using the bar that appears, so I train people to look for that bar to do any bulk update. Having to explain this as an exception and requiring a specific grouping to do a bulk update still sounds convoluted to me. Maybe convoluted is a strong word, but inconsistent at the least.
Also, last time I checked multi-select didn’t work with board view, which I commonly use for process workflows.
EDIT: I checked. Apparently using ctrl it works. Still would like to do it with shift though: FEATURE REQUEST: Be able to select multiple tickets with shift in board view
For reference projects I think this is less intuitive, which is my use-case a.t.m.
And another factor is that the people working in this specific project don’t do a lot of work in Asana yet, so I have an extra motivation to keep it as simple as possible.
