You can only collapse an expanded expense by clicking exactly horizontal with the expense total
I just noticed that the only area listening for a click to collapse an expanded expenses is a thin strip exactly parallel with with amount total of the expense. It would be nice if clicking anywhere in the expanded expense header collapsed the expense.
Very interesting suggestion! That is by design, but I’m curious to see if other people agree. Personally, I like they way it works but I’ll leave this under review to think about as we are tweaking design.
